Genesis 17:1-9

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. I will make you abundantly fruitful, more than you expect. I will make nations out of you, and kings will trace their lineage back to you. Yes, I will establish my eternal covenant of love between me and you, and it will extend to your descendants throughout their generations. I will be your children’s God, just as I am your God. I will give to you and your seed the land to which you have migrated. The entire land of Canaan will be yours and your descendants’ as an everlasting possession. And I will be their God forever!” God explained to Abraham, “Your part of the covenant is to obey its terms, you and your descendants throughout the ages.
