Genesis 18:9-15 - Sarah Laughs
9 And they said unto him, Where is Sarah your wife? And he said, Behold, in the tent.
10 And he said, I will certainly return unto you according to the time of life; and, lo, Sarah your wife shall have a son. And Sarah heard it in the tent door, which was behind him.
11 Now Abraham and Sarah were old and well stricken in age; and it ceased to be with Sarah after the manner of women. 12 Therefore Sarah laughed within herself, saying, After I have grown old shall I have pleasure, my lord being old also?
13 And the LORD said unto Abraham, Why did Sarah laugh, saying, Shall I of a certainty bear a child, who am old? 14 Is anything too hard for the LORD? At the time appointed I will return unto you, according to the time of life, and Sarah shall have a son.
15 Then Sarah denied, saying, I laughed not; for she was afraid. And he said, Nay; but you did laugh.
