Genesis 15 – God makes a covenant with Abram telling him that even though is presently childless, he will have an heir of his own body and his descendents will be too many to count, like the stars.
God told him that his descendants will be enslaved and mistreated four hundred years, God will punish the nation they serve as slaves, and afterward his descendants will come out with great possessions. Abram will go to his fathers in peace and be buried at a good old age. In the fourth generation, Abram’s descendants will come back here, for the sin of the Amorites has not yet reached its full measure. The LORD made a covenant with Abram and said, “To your descendants I give this land, from the river of Egypt to the great river, the Euphrates– the land of the Kenites, Kenizzites, Kadmonites, Hittites, Perizzites, Rephaites, Amorites, Canaanites, Girgashites and Jebusites.”
