Genesis 18:12-14

King James Version

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

¹³ And the Lord said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, which am old?

¹⁴ Is 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.
