Genesis 17:20-22 Living Bible (TLB)
20 As for Ishmael, all right, I will bless him also, just as you have asked me to. I will cause him to multiply and become a great nation. Twelve princes shall be among his posterity. 21 But my contract is with Isaac, who will be born to you and Sarah next year at about this time.”
22 That ended the conversation and God left.
