Genesis 15

Genesis 15 is mainly a confirmation of the Abrahamic Covenant in which God promised that Abraham’s descendents will inherit the land of Canaan. It also predicts the 400 year sojourn in Egypt of the Children of Israel and God’s promise to bring them out of Egypt to the land of Canaan to then inherit it. Given Abraham’s advanced age and childlessness at this point a scientific look at the situation would say that this promise was impossible by natural means, particularly with the advanced age of his wife.
