1-Job lived after the flood. Eliphaz, his friend and also his accuser, gave us a clue to this fact. Eliphaz asked: “Will you keep to the old way which wicked men have trod, who were cut down before their time, whose foundations were swept away by a flood?” (ch. 22:16).
2-Job lived during the Patriarchal era because the life span of his life was rather long and matched the life span of the patriarchal people who lived around 2200 B.C (Genesis 11:22-23). For before his trial, he had 10 adult children. Then, after his trial, he married and God blessed him with 10 more children and double the riches he had before (ch. 42:10-13). And the Bible adds: “After this Job lived one hundred and forty years, and saw his children and grandchildren for four generations. So, Job died, old and full of days” (ch. 42:10-17). Thus, it seems that he lived at least 200 years or more.
3-Job lived before the Mosaic era because his book does not mention of the Levitical priesthood, the temple, or the Law of Moses. Like the patriarch Abraham (Genesis 8:20; 12:7-8; 31:54), he offered up sacrifices to God on behalf of his family (ch. 1:5) as the head of his clan.
4-Another indication that Job lived in the Patriarch era is that his riches were measured by livestock and not by money (ch. 1:3; 42:12). Later during the Mosaic era, people used coins more frequently for trading.
5-Also another pointer that Job lived during the patriarchal era is that unlike the era of the Mosaic law that gave inheritance to daughters only when there were no males sons, he gave his daughters “an inheritance among their brothers” (ch. 42:15).
