What years was Job on Earth?
While the Bible doesn’t date the time of Job, internal references in the book suggest he lived around the time of the patriarchs of Abraham, Isaac, and Jacob (beginning about 2100 B.C.).
For example, Job's length of his life (he lived 140 years after his trials ended, 42:16) is similar to that of Terah (205 years), Abraham (175 years), Isaac (180 years), and Jacob (147 years). Also, the writer measured Job's wealth in terms of his livestock, which is how Moses evaluated the wealth of Abraham and Jacob (1:3; 42:12; compared to Gen 12:16; 13:2; 30:43; 32:5). Thirdly, the Sabeans and Chaldeans (1:15, 17) were nomads during the patriarchal period, but not later. Finally, the Hebrew word for "piece of silver [money]" (qesitah; 42:11) is found elsewhere only in connection with Jacob (Gen. 33:19).
