Q: Please who was older between Job and Moses? Where in the Bible can I find verses to show who was older?
A: Are you asking which came first or who lived the longest?
Most Bible scholars believe that Job was written before Moses came along. In fact many think that Job is the oldest book in the Bible though Moses writes about the beginning and a much earlier time in the Book of Genesis.
Other than the Book of Job and a reference in Ezekiel (14:14,20) the man Job is not mentioned anywhere else in the Bible. So there is no particular Bible verse that would prove it one way or another but the culture in the Book of Job reflects an earlier time frame (Patriarch Period) than that of Moses.
Who Lived the longest? Job.
According to the Book of Job (42: 16) he lived 140 years after the trouble recorded in the book and was ‘full of days’ and saw 4 generations of his posterity. Since in the beginning of the book he was already a mature man with adult children he probably lived for more than 180 years at least.
Moses lived to be 120 years old according to Deut. 34:7.
