At first glance, an answer to this question [When did the Exodus Occur?] seems to be available from chronological indications in the biblical narrative itself. We are told that Abraham was 75 years old when he set out for Canaan (Genesis 12:4) and 100 when Isaac was born (Genesis 21:5). According to Genesis 25:26, Isaac was 60 years old when Jacob was born. Then, if Jacob was 130 when he descended into Egypt, as we read in Genesis 47:9, the full time the patriarchs spent in Canaan before going to Egypt was 215 years.
Subsequently, we are told that the period of slavery in Egypt lasted 430 years (Exodus 12:40), and that the time from the Exodus from Egypt to the beginning of the construction of the Temple in the fourth year of Solomons reign was 480 years (1 Kings 6:1). This brings us close to the period where we have secure chronological information: Scholars agree that Solomon died within a decade or so of 930 B.C.E. According to 1 Kings 11:42, he reigned 40 years. It follows that his fourth year, the year work began on the Temple, was about 966 B.C.E. Reckoning backward from this date and using the numbers cited above, we arrive at the following scheme:
2091 B.C.E. Abrams departure for Canaan
1876 B.C.E. The descent of Jacobs family into Egypt
1447 B.C.E. The Exodus from Egypt
966 B.C.E. The beginning of Solomons Temple
