Genesis 26:3-5

26:3 Stay in this land. Then I will be with you and will bless you, for I will give all these lands to you and to your descendants, and I will fulfill the solemn promise I made to your father Abraham. 26:4 I will multiply your descendants so they will be as numerous as the stars in the sky, and I will give them all these lands. All the nations of the earth will pronounce blessings on one another using the name of your descendants. 26:5 All this will come to pass because Abraham obeyed me and kept my charge, my commandments, my statutes, and my laws.”
