Thematic Bible: Again disbelieves God's promise

So Sarah laughed to herself saying, "After I am worn out and my husband is old, shall [this] pleasure be to me?" Then Yahweh said to Abraham, "What [is] this [that] Sarah laughed, saying, 'Is it indeed true [that] I will bear a child, now [that] I have grown old?' Is anything too difficult for Yahweh? At the appointed time I will return to you {in the spring} and Sarah [shall have] a son." read more.
But Sarah denied [it], saying, "I did not laugh," because she was afraid. He said, "No, but you did laugh."
