Genesis 17:1-6

When Abram was ninety-nine years old, the LORD appeared to him and said, “I am God Almighty. Obey me and do what is right. 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.
