Stephen ArmstrongIsrael is camped a short distance from the mountain of God
We’re building toward the moment when Moses will reach Sinai and ascend the mountain to meet with God
Until that moment, we’re still watching the Lord bring Israel experience after experience
The experiences are teaching opportunities for Israel
They are being introduced to their Lord in stages
They’ve seen His wonders and powers of destruction in Egypt
And they’ve seen His faithfulness to provide for His people
Last week we saw the Lord providing food and water
Manna and water pouring from a rock
These provisions were designed to create pictures of the Lord
The food from Heaven was intended to draw comparisons to Jesus, the Bread of Life from Heaven
He sustains us spiritually, making possible eternal life
We studied in John 6 how Jesus compared Himself to the manna
The manna God delivered left Israel hungry later
And they eventually died despite that manna
So it wasn’t the ultimate solution to their need
But it pictured a great solution, that is Christ
Jesus also comes from Heaven and must be taken in
But when we accept Him, we receive a new life that will never die
We also looked at the water from the Rock, but our study ended before we had time to make a connection between the water from the Rock and Jesus
The water came from a rock that was split in two when Moses struck it with his staff
Then water gushed forth creating a river that eventually made a lake of fresh water for Israel’s encampment
The rock itself is a picture of Christ
The rock at Horeb was real, and real water poured out of it in a supernatural way
But God determined to provide water in this unique way to create this picture of Christ for later generations
We should understand Jesus as the One Who gives us living water, that is a living spirit
And from that new spirit, living water will spill out of us
In fact, a rock in some form is the most common symbol used to depict Christ
At various times Christ is described symbolically as a rock, stone, block, mountain, or cornerstone
These symbols often have unique features that teach us things about Jesus
Stones that have not be cut by human hands
Stones that have been tested
Stones that are foundations or cornerstones of a building
A stone or rock of offense that some stumble over
Furthermore, the rock was struck by the staff God gave Moses
Moses’ staff has already become a symbol of the Father’s authority
All the major miracles the Lord performed through Moses were performed using Moses’ staff
The message has become clear to the people of Israel that the work done through that rod is the work of God through Moses
So as Moses struck the rock, a picture is formed of God the Father ordering that the Rock, His Son, be struck for the benefit of the people
By striking Christ, the Father will bring a river of life flowing to His people
So Christ was struck (or afflicted) for our sake, just as the rock was struck by the rod God gave Moses
God wanted the rock struck (as opposed to some other method) so that this picture would be available
Finally, this moment also parallels one of the stories of John’s Gospel
In chapter 4, Jesus meets a woman at a well, and the discussion turns to the importance of water from the well
The woman talks about the need for physical water, water that our flesh thirsts for
Meanwhile, Jesus talks about a different kind of water, spiritual refreshment that leads to everlasting life
Isn’t it interesting that our descriptions of Hell always include images of heat and burning
Where the sufferers long for a drop of water
And in contrast, the believer is told that faith brings eternal flowing rivers of water that bring everlasting refreshment
Moving forward in the story, we turn back to the end of chapter 17 to find the nation still moving toward the mountain of God
And as they move into place, they come under attack
The nation of Israel comes under attack for the first time since leaving Egypt, and really for the first time ever
The attacker is a man called Amalek, and he leads a tribe called the Amalekites
They attack at Rephidim, which is an encampment of Israel near the mountain of God
Amalek is the great grandson of Isaac through Esau
So he is essentially a distant cousin with the Israelites
We must assume he was threatened by the sudden appearance of 2+ million people entering into his land
We aren’t given the details of the attack in this chapter, but later the Lord reminds Moses of this event in Deut 25 and gives a consequence to the Amalekites
Apparently, Amalek chose to attack Israel from the rear as they were moving into the camp
The people of Israel were weary after a day of travel
And there were stragglers at the back of the assembly who were vulnerable to the attack
This was a cowardly way to attack Israel
Moreover, Amalek showed no fear of God in his attack
We must remember that people everywhere had heard of the Lord’s destruction of Egypt and His rescue of Israel
They would have also learned of the Pharaoh’s destruction at the Red Sea crossing
Nevertheless, Amalek was still willing to attack God’s people, thus showing no fear of God
Then a battle ensues
To lead the fight, Moses turns to a young man named Joshua
This is the first mention of Joshua in the Bible
He becomes a major Biblical character
One book of scripture is named for him
His name was not originally Joshua
In the genealogy of Numbers 13, we see his name given as Hoshea
Hoshea means savior
Later, Moses changes his name to Joshua
Joshua means the Lord is savior
When the Hebrew word “Joshua” is translated into Greek and then from Greek into English, it becomes Jesus
In other words, Jesus and Joshua are the same name, which means the Lord saves
Joshua will become a private servant to Moses
In Ex 24 we learn that Joshua has been given this role
He also becomes Moses’ successor who leads Israel into Canaan
It’s no accident that Joshua would be mentioned in the same chapter where the rock is struck for water
As we studied earlier in this chapter, Moses was instructed to strike a rock and water came out
And as we noted, the rock itself pictures Jesus
The striking of the rock reflects Jesus’ having been “struck” (i.e., dying) on the cross for the sins of men
So the first part of Exo 17 taught us that just as Moses struck the rock to save Israel, so did God the Father strike His Son to save God’s children from sin
Later in Numbers 20, there will come yet another time when God will produce water from a rock in response to Israel’s complaints
In that future incident, God will instruct Moses to speak to the rock and water will come forth
In his disgust and anger at Israel’s grumbling, Moses impatiently strikes the rock with his rod just as he had done before in Ex 17
This action was not in keeping with God’s instructions
And so the Lord becomes angry at Moses for his disobedience
How are these events related to Joshua’s appearance in the second half of Ex 17?
As a result of Moses’ disobedience later in Number, Joshua is appointed as Israel’s leader
Furthermore, as a result of Moses’ disobedience, God disciplined Moses by denying him opportunity to enter into the Promised Land
Moses would die in the desert
In his place, Joshua was to lead Israel into the Promised Land
So Joshua is introduced in connection with the striking of the rock because in a later day, Joshua will supplant Moses in connection with a similar incident
The rock of water and Joshua become closely connected by that later incident
One explains the rise of the other
You might wonder why was God so upset at Moses’ disobedience?
When Moses struck the rock a second time, Moses was distorting the picture the Lord was intent on creating through the rock
Moses’ actions were suggesting that the Messiah Himself would need to be struck a second time by God the Father to save Israel
In truth, Jesus must die only once for our sins and will never again be struck in that way
When the Messiah comes again, He comes in power and glory, not to be struck by a rod but to rule with a rod of iron
Yet Moses’ disobedience potentially corrupted that picture, forcing God to discipline Moses in order to make clear that his actions were wrong
This fact makes possible an even more powerful understanding of Joshua’s connection to the rock of water
Moses brings Israel the Law, and as a result Moses comes to represent the Law in scripture
We even call it the Law of Moses
The purpose of the Law according to scripture is to act as a witness against the people of Israel
Paul tells us that Law was not given to produce righteousness
The Law was given to reveal unrighteousness by showing us to be guilty of disobedience
Therefore, no man will be saved by works of Law, Paul tells us
So when the man who represents the Law is himself shown to be a lawbreaker, he forms an unintentional picture that God uses for His own purposes
Moses, the Law giver, is not qualified to lead Israel into the Promised Land
In other words, the Law brings no one into the Promised Land, which is another term for the kingdom
Should we try to enter the kingdom by works of the Law, we will be found to be a sinner and thereby be disqualified and prevented from entering
So Moses’ failure pictures the Law’s failure to bring us to righteousness and into the Kingdom
Instead of Moses, it was Joshua who leads Israel into the Promised Land
Joshua, as you know, is the same name as Jesus
Jesus is the One Who leads us into salvation and into the Kingdom
He is the door by which we enter the kingdom of God
Jesus called Himself that door
So as Joshua led Israel into the Promised Land, so does Jesus lead us into salvation and the Kingdom
So Moses introduces us to Joshua at this point to emphasize that Joshua will be the future leader of Israel
Turning to the battle itself, as Joshua takes some of the people of Israel and begins to engage the Amalekites, Moses stations himself on a hill overlooking the battle
With him are his brother, Aaron, and Hur
Hur was said to the be Moses’ brother-in-law,, the husband of Miriam, according to Josephus
Israel had strength in numbers, while the Amalekites probably had the benefit of better equipment and experience in battle
But Israel had an even more powerful advantage
They had Charlatan Heston’s underarms
As Moses watches the battle, he finds that he has an ability to intercede on behalf of Israel
When Moses raises his hands to the Lord, the battle goes Israel’s way, but when his hands drop, Amalek begins to win the battle
We don’t know how Moses came to discover this connection
We assume he was naturally directed to pray on behalf of Israel, and he raised his hands when he prayed
At some point he grew weary and ceased praying
That’s when he noticed that his intercession was crucial to the battle
Once Moses and his companions notice the connection, they immediately understand what they must do
They must remain in constant prayer until the battle is won
To achieve this physically straining endeavor, they assist Moses by holding his hands when his own arm muscles give out
We know that the Lord didn’t need Moses’s hands to be raised in order to defend Israel, so why did God insist on such a contrived method?
Once again, God’s purpose is to teach Israel and later generations concerning the Lord
First, remember this is the first military battle for Israel, and therefore it’s the first time Israel will experience the Lord fighting for them in human combat
The men of Israel are the ones physically engaged in the fighting
But the Lord will steer the events of the battle to His desired outcome
This is the same way Gideon defeats a huge army with only 300 men
In fact, battles will occur frequently in Israel’s wanderings and conquest of Canaan, and all the battles will be fought under Joshua’s leadership
So this first battle will set an important precedent for the nation
When Israel prevails, who will they credit?
Joshua? Moses? The Lord? Who is responsible for the outcome?
So to ensure the nation appreciates the Lord’s grace and provision of victory, the Lord chooses to work through Moses’ staff in a very visible way
As Moses holds his staff skyward with hands raised in full view of all the nation, Joshua prevails
The staff continues to serve as a symbol of God’s power and authority
So the message to Israel is that the Lord was the One earning Joshua his victory
When Moses drops the staff by the lowering of his hands, the nation ceases to prevails
In that way the people understand that Joshua and the men are not strong enough by their own power to win the battle
Human ability is not the deciding factor...the Lord is their secret weapon
These scene is often thought to be one of the best picture of intercessory prayer available in scripture
This account never says explicitly that Moses was praying, but it seems a reasonable assumption he may have offered prayer on behalf of Joshua
Even if Moses never prayed himself, the entire scene remains a beautiful example of men seeking God’s intercession
First, it reflects the true purpose of prayer
Too often we assume that prayer is an attempt on our part to persuade God to do our bidding
But God’s will doesn’t bend to the hearts of men
God’s heart is to bend the will of men
The true purpose of prayer is to bring our needs before God in the hope of receiving His grace and mercy in some way
Perhaps we will receive exactly what we request
Maybe the Lord will give us a different solution or nothing at all
Whatever He does, it will be the best thing we could receive
In the meantime, we will know it came from the Lord
In fact, our prayer life will become the means to glorify God in the same way Moses’ hands glorified the Lord
His intercession gave opportunity for Moses and the people to see the Lord working and give Him glory for it
Without the intercession, the work would still happen, but would we have known to credit the Lord?
Perhaps we would have wasted time praising Joshua for being such a great warrior
Prayer is a billboard God will use to tell the world of His work on behalf of His children
When we spend time seeking Him, then we have opportunity to connect the dots between our desires and His goodness
This is why James says:
James isn’t teaching that we always get what we ask
But he is teaching that until we become proficient in seeking God for our needs, we can’t mature into the person who asks for the right things in the right ways and thereby sees the fruit of God’s provision
We could make further comparisons to the role of partners in prayer, as illustrated by Aaron and Hur
And to the need to pray constantly and not just sporadically
But the points are obvious
So Joshua prevails
The Lord commands Moses to begin writing a book
This is the first time of five time we hear the Lord telling Moses to write something
It’s interesting - but probably not meaningful - that Moses eventually wrote five books in the Torah
Nevertheless, this is the first time Moses begins to write and sets Moses on the path to record God’s word
In this case, Moses is told to record this event with a promise from God to blot out the memory of Amalek under Heaven
Furthermore, the Lord will war with Amalek in the meantime
Joshua later encounters the Amalekites in Canaan when Israel enters the land
At that time, the Lord orders Joshua to exterminate this people at that time
Nonetheless, some live on but are eventually destroyed under Hezekiah
Amalek’s fate is another teaching moment for Israel
Just as God has given Israel promises of future eternal glory, peace and possession of an inheritance, He is also promising eventual end to Israel’s enemies
Notice Moses is told to repeat these words in Joshua’s hearing, indicating that God wants this moment to be clearly understood by Joshua
Joshua and Israel are to have confidence to know that Israel’s enemies will not only be defeated, but they will cease to exist one day
This is still true today
The enemies of Israel still have the upper hand, but in a future day, they will be exterminated from the earth
Finally, a memorial is erected to the Lord’s victory
Moses builds an altar at the base of the mountain of Horeb
He names it the Lord is my banner, which refers to a military victory
So Moses declares that the Lord is the One Who gives victory in battle
Mose declares what the Lord instructed
The Lord has sworn to battle against Amalek, and this battle will last for generations
In fact, it lasts for four centuries before the people are wiped out
For a time in Judges, the Amalekites manage to win victories over parts of Israel until Gideon defeats them again
Later Saul defeats the Amalekites so badly they never again have national status or strength
After they win the battle, Israel settles in for a time at the mountain, giving opportunity for Moses’ family to arrive for a visit from elsewhere in Midian
Ex. 18:1 Now Jethro, the priest of Midian, Moses’ father-in-law, heard of all that God had done for Moses and for Israel His people, how the LORD had brought Israel out of Egypt.
Ex. 18:2 Jethro, Moses’ father-in-law, took Moses’ wife Zipporah, after he had sent her away,
Ex. 18:3 and her two sons, of whom one was named Gershom, for Moses said, “I have been a sojourner in a foreign land.”
Ex. 18:4 The other was named Eliezer, for he said, “ The God of my father was my help, and delivered me from the sword of Pharaoh.”
Ex. 18:5 Then Jethro, Moses’ father-in-law, came with his sons and his wife to Moses in the wilderness where he was camped, at the mount of God.
Ex. 18:6 He sent word to Moses, “I, your father-in-law Jethro, am coming to you with your wife and her two sons with her.”
Ex. 18:7 Then Moses went out to meet his father-in-law, and he bowed down and kissed him; and they asked each other of their welfare and went into the tent.
Ex. 18:8 Moses told his father-in-law all that the LORD had done to Pharaoh and to the Egyptians for Israel’s sake, all the hardship that had befallen them on the journey, and how the LORD had delivered them.
Ex. 18:9 Jethro rejoiced over all the goodness which the LORD had done to Israel, in delivering them from the hand of the Egyptians.
Ex. 18:10 So Jethro said, “ Blessed be the LORD who delivered you from the hand of the Egyptians and from the hand of Pharaoh, and who delivered the people from under the hand of the Egyptians.
Ex. 18:11 “Now I know that the LORD is greater than all the gods; indeed, it was proven when they dealt proudly against the people.”
Ex. 18:12 Then Jethro, Moses’ father-in-law, took a burnt offering and sacrifices for God, and Aaron came with all the elders of Israel to eat a meal with Moses’ father-in-law before God.
Jethro, Moses’ father-in-law heard of everything happening to Moses and the people, and so he travels to visit Moses
He brings Moses’ wife and boys to visit Moses
Remember, Zipporah was sent back to Midian at the incident of the circumcision
She wasn’t a part of the work of Moses in Egypt
It’s worth remembering that she missed the chance to witness all of God’s miraculous work
She missed it because of her unwillingness to support Moses in obeying God’s word
We also learn the names of Moses’ sons
The first name, Gershon, was known already
But now we know the second son was named Eliezer, meaning the Lord is my help
Jethro sends word ahead of his arrival, so Moses shows Jethro respect by going out to meet him and welcomes Jethro into his tent
Moses then relates the entire event of the Exodus to Jethro
It must have been an incredible story
Jethro must have been wide-eyed throughout the account
This was better than any Hollywood movie...well, almost better than any Hollywood movie
Jethro responds in some important ways
First, he rejoices over Israel’s deliverance in v.9
This tell us that he had a heart to bless those the Lord has blessed and to love those the Lord loves
Secondly, he praises the Lord and credits Him with this work in v.10
This suggests to us that Jethro is now convinced in the power and faithfulness of the Hebrew God
Then, he makes a confession in v.11
He declares that God was above all other gods
Finally, in v.12 Jethro makes a sacrifice to the Lord and an offering of thanks
What do we make of Jethro’s actions?
Some believe this proves Jethro either was a priest of the Jehovah or becomes a follower of God at this point
Others point out that In Num 25:17-18 Midianites were described as pagans and worshippers of many gods
You can find support for both views in the text
Then Jethro makes a contribution to Moses’ work
Ex. 18:13 It came about the next day that Moses sat to judge the people, and the people stood about Moses from the morning until the evening.
Ex. 18:14 Now when Moses’ father-in-law saw all that he was doing for the people, he said, “What is this thing that you are doing for the people? Why do you alone sit as judge and all the people stand about you from morning until evening?”
Ex. 18:15 Moses said to his father-in-law, “Because the people come to me to inquire of God.
Ex. 18:16 “When they have a dispute, it comes to me, and I judge between a man and his neighbor and make known the statutes of God and His laws.”
Ex. 18:17 Moses’ father-in-law said to him, “The thing that you are doing is not good.
Ex. 18:18 “ You will surely wear out, both yourself and these people who are with you, for the task is too heavy for you; you cannot do it alone.
Ex. 18:19 “Now listen to me: I will give you counsel, and God be with you. You be the people’s representative before God, and you bring the disputes to God,
Ex. 18:20 then teach them the statutes and the laws, and make known to them the way in which they are to walk and the work they are to do.
Ex. 18:21 “Furthermore, you shall select out of all the people able men who fear God, men of truth, those who hate dishonest gain; and you shall place these over them as leaders of thousands, of hundreds, of fifties and of tens.
Ex. 18:22 “Let them judge the people at all times; and let it be that every major dispute they will bring to you, but every minor dispute they themselves will judge. So it will be easier for you, and they will bear the burden with you.
Ex. 18:23 “If you do this thing and God so commands you, then you will be able to endure, and all these people also will go to their place in peace.”
Ex. 18:24 So Moses listened to his father-in-law and did all that he had said.
Ex. 18:25 Moses chose able men out of all Israel and made them heads over the people, leaders of thousands, of hundreds, of fifties and of tens.
Ex. 18:26 They judged the people at all times; the difficult dispute they would bring to Moses, but every minor dispute they themselves would judge.
Ex. 18:27 Then Moses bade his father-in-law farewell, and he went his way into his own land.
Jethro observes as Moses take on the duties of a judge in Israel
It is understandable to see Moses assume this role
Israel consists of 2 million people but without lines of authority or government
They are living in a commune and taking orders from Moses, who receives them from the Lord
Inevitably, a group of 2 million people will encounter disputes, various forms of lawlessness, etc.
Someone must judge over these matters, and Moses naturally assumes he must accomplish this work
Furthermore, Moses was receiving instructions from God on a regular basis, and these instructions were handed down to the people by Moses
Since there was no email, and no megaphones, Moses was literally communicating instructions to all 2 million people
Evidently, he passed out instructions to one group and then another
In v.13 we learn that Moses was forced to serve in this way from morning until evening
And Jethro correctly determines that this won’t work for long
Moses is hoping he can hold out, but Moses needs a plan, and hope is not a plan
So Jethro takes it upon himself to point out the flaws in Moses’ system
First, he says this is not good, or beneficial
It is not beneficial for Moses or for the people
Moses has too much burden to bear and must include others in the work
Secondly, the work Moses chooses for himself must be the work he alone is qualified to handle, that is the work of a prophet
Moses is to act as God’s representative, since this is the role God assigned to Moses
His work should focus on teaching God’s statutes and laws and exhorting them to walk in these ways
Finally, he is to appoint trustworthy men to work alongside him at lower levels of authority in a chain of command
These lower officials will handle most issues and only bring the most serious ones before Moses
Jethro assures Moses that is he will benefit from this change as well the people
Moses will be able to endure and sustain his work
The people will receive quicker, easier resolution to their disputes
It should be clear to us all that these instructions set a wise precedent for spiritual leaders in the church today
First, leaders are not supposed to go it alone in ministry
They should work within a plurality of leadership over congregations
If one man tries to do it all, he repeats Moses’ mistake
Secondly, leaders should know their spiritual gifts and calling, and then remain focused on them while resisting the temptation to do other things
The senior leader(s) has a primary responsibility to train up the body in the word of God and to exhort our people to live according to it
If leaders let other duties come between them and teaching the word, they begin to fail the Acts 6 test
They forsake the teaching of God’s word to feed the widows
If our people learned the Bible and lived by it, every other issue we face as leaders would diminish if not disappear altogether
Thirdly, we should establish some degree of hierarchy of leadership in the church
Multiple levels of leadership support the efficient operation of the body
Remembering that levels of leadership doesn’t imply a bunch of employees and staff receiving support from the congregation
Next week we move with Israel to the mountain of Sinai
