Genesis 18:12

They asked him, “Where is Sarah, your wife?”

He said, “There, in the tent.”

He said, “I will certainly return to you at about this time next year; and behold, Sarah your wife will have a son.”

Sarah heard in the tent door, which was behind him.

Now Abraham and Sarah were old, well advanced in age. Sarah had passed the age of childbearing.

The LORD said to Abraham, “Why did Sarah laugh, saying, ‘Will I really bear a child when I am old?’

Is anything too hard for the LORD? At the set time I will return to you, when the season comes around, and Sarah will have a son.”

Then Sarah denied it, saying, “I didn’t laugh,” for she was afraid.

He said, “No, but you did laugh.”
