18So Abraham said to God, “May Ishmael live under your special blessing!”
19But God replied, “No—Sarah, your wife, will give birth to a son for you. You will name him Isaac, and I will confirm my covenant with him and his descendants as an everlasting covenant.
20As for Ishmael, I will bless him also, just as you have asked. I will make him extremely fruitful and multiply his descendants. He will become the father of twelve princes, and I will make him a great nation.
21But my covenant will be confirmed with Isaac, who will be born to you and Sarah about this time next year.”
