Genesis 22:17-18

So I will do really good things for you. And I will give you a really big family. You see, lots of people will be born into your son’s family later on, and they will become a really big mob of people. There will be lots and lots of them, just like there are lots of stars in the sky, and lots of little bits of sand at the beaches beside the sea. And when other nations get up to fight against them, your family will win, and they will take the towns from those other nations. And I will use your family to do good things for all the nations in the world. I will do all this because you listened to me, and you did what I told you to do.’ ”
