Genesis 18:9-15

9Then they asked him, “Where is Sarah your wife?” He replied, “There, in the tent.”

10One of them said, “I will surely return to you when the season comes round again, and your wife Sarah will have a son!” (Now Sarah was listening at the entrance to the tent, not far behind him.

11Abraham and Sarah were old and advancing in years; Sarah had long since passed menopause.)

12So Sarah laughed to herself, thinking, “After I am worn out will I have pleasure, especially when my husband is old too?”

13The Lord said to Abraham, “Why did Sarah laugh and say, ‘Will I really have a child when I am old?’

14Is anything impossible for the Lord? I will return to you when the season comes round again and Sarah will have a son.”

15Then Sarah lied, saying, “I did not laugh,” because she was afraid. But the Lord said, “No! You did laugh.”
