Genesis 18:12-15

18:12 So Sarah laughed to herself, thinking, “After I am worn out will I have pleasure, especially when my husband is old too?”

18:13 The Lord said to Abraham, “Why did Sarah laugh and say, ‘Will I really have a child when I am old?’ 18:14 Is anything impossible for the Lord? I will return to you when the season comes round again and Sarah will have a son.” 18:15 Then Sarah lied, saying, “I did not laugh,” because she was afraid. But the Lord said, “No! You did laugh.”
