God’s covenant with Abraham

17 When Abram was 99 years old, the Lord appeared to Abram and said to him, “I am El Shaddai.^[a] Walk with me and be trustworthy. ² I will make a covenant between us and I will give you many, many descendants.” ³ Abram fell on his face, and God said to him, ⁴ “But me, my covenant is with you; you will be the ancestor of many nations. ⁵ And because I have made you the ancestor of many nations, your name will no longer be Abram^[b] but Abraham.^{[c] 6} I will make you very fertile. I will produce nations from you, and kings will come from you. ⁷ I will set up my covenant with you and your descendants after you in every generation as an enduring covenant. I will be your God and your descendants’ God after you. ⁸ I will give you and your descendants the land in which you are immigrants, the whole land of Canaan, as an enduring possession. And I will be their God.”

⁹ God said to Abraham, “As for you, you must keep my covenant, you and your descendants in every generation. ¹⁰ This is my covenant that you and your descendants must keep: Circumcise every male.

¹⁵ God said to Abraham, “As for your wife Sarai, you will no longer call her Sarai. Her name will now be Sarah. ¹⁶ I will bless her and even give you a son from her. I will bless her so that she will become nations, and kings of peoples will come from her.”

¹⁷ Abraham fell on his face and laughed. He said to himself, Can a 100-year-old man become a father, or Sarah, a 90-year-old woman, have a child? ¹⁸ To God Abraham said, “If only you would accept Ishmael!”

¹⁹ But God said, “No, your wife Sarah will give birth to a son for you, and you will name him Isaac.^[a] I will set up my covenant with him and with his descendants after him as an enduring covenant. ²⁰ As for Ishmael, I’ve heard your request. I will bless him and make him fertile and give him many, many descendants. He will be the ancestor of twelve tribal leaders, and I will make a great nation of him. ²¹ But I will set up my covenant with Isaac, who will be born to Sarah at this time next year.”
