Genesis 17:20-22

New Catholic Bible

²⁰ As for Ishmael, I have heard you. Behold, I will bless him and make him fruitful and very, very numerous. Twelve princes shall come from him and I will make him a great nation. ²¹ But I will establish my covenant with Isaac. Sarah shall give birth to him by this time next year.” ²² God thus finished speaking to Abraham, and rising into the heavens, he left him.
