Genesis 17 : 1, 9-10, 15-22
When Abram was ninety-nine years old, YHVH appeared to him and said, “I am God Almighty. Walk in My presence and be without blame! For your part, you shall keep My covenant, you and your descendants after you, generation after generation. This is My Covenant with you, that you will keep, you and your descendants after you : Every male among you shall be circumcised.”
God said to Abraham, “As for Sarai, your wife, no longer are you to call her Sarai, but Sarah. I will bless her, and I will give you a son by her. I will bless her and from her will come nations; kings and peoples shall come from her.”
Then Abraham fell face down, and he laughed and said to himself, “Will a son be born to a man a hundred years old? And can Sarah who is ninety have a child?” And Abraham said to God, “If only You would accept Ishmael as Yours!” But God said, “Not at all! It is Sarah, your wife, who will give birth to your son and you will name him Isaac. I will establish My Covenant with him and his descendants after him forever.”
“As for Ishmael, I heard you. I will bless him and make him fruitful, and I will multiply his race. He shall be the father of twelve princes and I will make of him a great nation. But My Covenant I will establish with Isaac, the child Sarah will have this time next year.” When He had finished speaking with Abraham, God went away from him.
