Genesis 17:1-5

When Abram was ninety-nine years old, YAHWEH appeared to him again and said, “I am the God who is more than enough. Live your life in my presence and be blameless. I will confirm my covenant between me and you, and I will greatly multiply your descendants.” Then Abram fell on his face in awe before God, and God said to him, “I establish my covenant with you: “You will become a father of many nations. You will no longer be named Abram because I am changing your name to Abraham, for I have made you a father of many nations.
