Genesis 17:18-20 Common English Bible (CEB)
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.
