Genesis 18:13-15
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.”
