Genesis 18:10–15 NRSV 10 Then one said, “I will surely return to you in due season, and your wife Sarah shall have a son.” And Sarah was listening at the tent entrance behind him. 11 Now Abraham and Sarah were old, advanced in age; it had ceased to be with Sarah after the manner of women. 12 So Sarah laughed to herself, saying, “After I have grown old, and my husband is old, shall I have pleasure?” 13 The LORD said to Abraham, “Why did Sarah laugh, and say, ‘Shall I indeed bear a child, now that I am old?’ 14 Is anything too wonderful for the LORD? At the set time I will return to you, in due season, and Sarah shall have a son.” 15 But Sarah denied, saying, “I did not laugh”; for she was afraid. He said, “Oh yes, you did laugh.”
