What period of time did Job live in?

Answer 1

From the contents of Job's book we can work out an approximation, to within about 150 years, of the period of time in which he lived.

Job (Heb. אִיּוֹב, Iyov) lived in Uz, in Arabia. God said that there was no man alive like him, a truly righteous man of integrity (Job 1:8+). So it appears that he lived after the death of the godly man Joseph (about 1650 BCE) but before Moses had appeared on the scene as a prophet of God to lead the Israelites out of their captivity in Egypt. (See Job 1:6-12; 2:1-7)

The exodus, led by Moses, took place about 1500 BCE. So it seems that Job may have lived somewhere within that time slot, i.e. 1650 BCE to 1500 BCE.

The Bible confirms the existence and measure of Job as one of the most righteous persons that ever lived, his lawful and charitable life comparable to that of Noah and Daniel. (See Ezekiel 14:14)

NOTE

Job/Iob/Jashub (Heb. ישיב, Yov, ya-shuv ) the son of Issachar (Genesis 46:13, Numbers 26:24, 1 Chronicles 7:1) is unlikely to be the same man referred to in the book of Job. Even though this son of Issachar occupied a similar time frame, somewhere from about 1750 BCE and dying around 1500 BCE, the Hebrew names are different.
