Genesis 22:17-18

Because you have done this, I will bless you. I will make your descendants become so many that people cannot count them. They will be as many as the stars that are in the sky. They will be as many as the pieces of sand on the shore by the sea. Your descendants will win against their enemies and their enemies' cities. I will bless all the nations on the earth through your descendants. I will do this because you have obeyed me.’
