Genesis 18:12-15 English Standard Version (ESV)

12. So Sarah laughed to herself, saying, “After I am worn out, and my lord 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 hard for the Lord? At the appointed time I will return to you, about this time next year, and Sarah shall have a son.”

15. But Sarah denied it, saying, “I did not laugh,” for she was afraid. He said, “No, but you did laugh.”
