Genesis 17:20-22 World English Bible (WEB)
20 As for Ishmael, I have heard you. Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly. He will become the father of twelve princes, and I will make him a great nation. 21 But my covenant I establish with Isaac, whom Sarah will bear to you at this set time next year.”
22 When he finished talking with him, God went up from Abraham.
