Genesis 18:10-17

Then one of them said, “I will return to you about this time next year, and your wife, Sarah, will have a son!” Sarah was listening to this conversation from the tent. Abraham and Sarah were both very old by this time, and Sarah was long past the age of having children. So she laughed silently to herself and said, “How could a worn-out woman like me enjoy such pleasure, especially when my master—my husband—is also so old?” Then the LORD said to Abraham, “Why did Sarah laugh? Why did she say, ‘Can an old woman like me have a baby?’ Is anything too hard for the LORD? I will return about this time next year, and Sarah will have a son.” Sarah was afraid, so she denied it, saying, “I didn’t laugh.” But the LORD said, “No, you did laugh.” Then the men got up from their meal and looked out toward Sodom. As they left, Abraham went with them to send them on their way. “Should I hide my plan from Abraham?” the LORD asked.
