Genesis 17:1-11

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. So here is the sign of the covenant that you are to keep, so that it will endure between you and me and your descendants: circumcise every male among you. You must undergo cutting off the flesh of your foreskin as a special sign of the covenant between me and you.
