Genesis 18
10 Ref And he said, I will certainly come back to you in the spring, and Sarah your wife will have a son. And his words came to the ears of Sarah who was at the back of the tent-door.
11 Ref Now Abraham and Sarah were very old, and Sarah was past the time for giving birth.
12 Ref And Sarah, laughing to herself, said, Now that I am used up am I still to have pleasure, my husband himself being old?
13 Ref And the Lord said, Why was Sarah laughing and saying, Is it possible for me, being old, to give birth to a child?
14 Ref Is there any wonder which the Lord is not able to do? At the time I said, in the spring, I will come back to you, and Sarah will have a child.
15 Ref Then Sarah said, I was not laughing; for she was full of fear. And he said, No, but you were laughing.
