Genesis 17:20-22 New English Translation (NET Bible)
20 As for Ishmael, I have heard you. I will indeed bless him, make him fruitful, and give him a multitude of descendants. He will become the father of twelve princes; I will make him into a great nation. 21 But I will establish my covenant with Isaac, whom Sarah will bear to you at this set time next year.” 22 When he finished speaking with Abraham, God went up from him.
