Genesis 17:19

God said , No , but Sarah your wife shall bear you a son , and you shall call his name Isaac . I will establish my covenant with him as an everlasting covenant for his offspring after him.

Then God said, “Yes, but your wife Sarah will bear you a son, and you will call him Isaac. I will establish my covenant with him as an everlasting covenant for his descendants after him.

And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac : and I will establish my covenant with him for an everlasting covenant, and with his seed after him.
