Genesis 26:3-4

3Stay in this land for a while, and I will be with you and will bless you. For to you and your descendants I will give all these lands and will confirm the oath I swore to your father Abraham. 4I will make your descendants as numerous as the stars in the sky and will give them all these lands, and through your offspring Or seed all nations on earth will be blessed, Or and all nations on earth will use the name of your offspring in blessings (see 48:20)
