Genesis 18:12-15

So Sarah laughed to herself as she thought, “After I am worn out and my lord is old, will I now have this pleasure?” Then the LORD said to Abraham, “Why did Sarah laugh and say, ‘Will I really have a child, now that I am old?’ Is anything too hard for the LORD? I will return to you at the appointed time next year, and Sarah will have a son.” Sarah was afraid, so she lied and said, “I did not laugh.” But he said, “Yes, you did laugh.”
