Genesis 18:9-11

Amplified Bible

⁹ Then they said to him, “Where is Sarah your wife?” And he said, “There, in the tent.” ¹⁰ He said, “I will surely return to you at this ^[a]time next year; and behold, Sarah your wife will have a son.” And Sarah was listening at the tent door, which was behind him.^{(A) 11} Now Abraham and Sarah were old, well advanced in years; she was past [the age of] childbearing.
