Genesis 18:10-15

10Then He said, “I will most surely return to you in about a year’s time, surprisingly, Sarah your wife will have a son.” Sarah was listening at the entrance of the tent, which was behind Him.

11Now Abraham and Sarah were old, advanced in years—Sarah had stopped having the way of women.

12So Sarah laughed to herself, saying, “After I’ve grown decrepit, can I have desire—and my lord so old?”

13Then Adonai said to Abraham, “Why is it that Sarah laughed, saying, ‘Can I really give birth when I am so old?’

14Is anything too difficult for Adonai? At the appointed time I will return to you—in about a year—and Sarah will have a son.”

15Sarah denied it saying, “I didn’t laugh!” For she was afraid. But He said, “No—for you did laugh.”
