Genesis 17:18-20 New Century Version (NCV)
18 Then Abraham said to God, “Please let Ishmael be the son you promised.”
19 God said, “No, Sarah your wife will have a son, and you will name him Isaac.[a] I will make my agreement with him to be an agreement that continues forever with all his descendants.
20 “As for Ishmael, I have heard you. I will bless him and give him many descendants. And I will cause their numbers to grow greatly. He will be the father of twelve great leaders, and I will make him into a great nation.
