Commentaries:
Comparing Genesis 17:23; Exodus 12:41; and Galatians 3:16-18, we have evidence of a significant Genesis event that later became a festival date, and thus it is important to Christianity. Exodus 12:2-6 dates the Passover on the fourteenth of Abib. Israel left Egypt on the next day, the fifteenth. Verse 41 strongly suggests that the Exodus was 430 years to the very day from when Abraham made the covenant with God which was sealed by the patriarch's circumcision. Galatians 3 reinforces the link between the events of the Exodus (Paul sums them up in the term "the law," which was given about two months after leaving Egypt), the 430 years and God's covenant with Abraham. These verses confirm that the Abrahamic covenant, the introduction of circumcision, and Israel's going out of Egypt took place on Abib 15, the First Day of Unleavened Bread.
