Genesis 18:13

¹¹Now Abraham and Sarah were old and well stricken in age; and it ceased to be with Sarah after the manner of women.

¹²Therefore Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also?

— Genesis 18:13 —

¹⁴Is any thing too hard for the LORD? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son.

¹⁵Then Sarah denied, saying, I laughed not; for she was afraid. And he said, Nay; but thou didst laugh.
