Genesis 17:2-7

I will make an agreement between us, and I will make you the ancestor of many people.” Then Abram bowed facedown on the ground. God said to him, “I am making my agreement with you: I will make you the father of many nations. I am changing your name from Abram to Abraham because I am making you a father of many nations. I will give you many descendants. New nations will be born from you, and kings will come from you. And I will make an agreement between me and you and all your descendants from now on: I will be your God and the God of all your descendants.
