¹⁹ 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.

21 And the Lord visited Sarah as he had said, and the Lord did unto Sarah as he had spoken.

¹⁶ And he said, About this season, according to the time of life, thou shalt embrace a son. And she said, Nay, my lord, thou man of God, do not lie unto thine handmaid.

⁹ For this is the word of promise, At this time will I come, and Sarah shall have a son.
