Genesis 26:3-5

3 Reside in this land as an alien, and I will be with you, and will bless you; for to you and to your descendants I will give all these lands, and I will fulfill the oath that I swore to your father Abraham.
4 I will make your offspring as numerous as the stars of heaven, and will give to your offspring all these lands; and all the nations of the earth shall gain blessing for themselves through your offspring,
5 because Abraham obeyed my voice and kept my charge, my commandments, my statutes, and my laws."
