Working on firming up dates for patriarchs (teaching chronology of the OT this semester). Ran into a glitch. PREMISE - I started at I Kings 6:1 "And it came to pass in the four hundred and eightieth year after the children of Israel were come out of the land of Egypt, in the fourth year of Solomon's reign over Israel . . " Solomon reigned 970BCE, so 4 years in is 966BCE. Add 480 years to get the exodus at 1446BCE. That works for me. NEXT - went to Exodus 12:40 to count back from exodus. "Now the sojourning of the children of Israel, who dwelt in Egypt, was four hundred and thirty years." Added 430 years to 1446BCE and got 1876BCE for the beginning of the sojourn by Jacob. NOW THE PROBLEM - one of my students questioned me, quoting both an OT and NT verse that contradicted my figures! Genesis 15:13 "And he said unto Abram, Know of a surety that thy seed shall be a stranger in a land that is not theirs, and shall serve them; and they shall afflict them four hundred years; and also that nation, whom they shall serve, will I judge: and afterward shall they come out with great substance." Acts 7:6 "And God spake on this wise, That his seed should sojourn in a strange land; and that they should bring them into bondage, and entreat them evil four hundred years. And the nation to whom they shall be in bondage will I judge, said God: and after that shall they come forth, and serve me in this place." This adds only 400 years to 1446BCE, making the beginning of Jacob's sojourn at 1846BCE. And obviously throws off all my dates for Isaac and Abraham by 30 years. Thoughts?
