Genesis 18:9-15 - Sarah Laughs
9 The men asked him, "Where is your wife Sarah?" "There, in the tent," he replied.
10 Then one of them said, "I will certainly return to you in about a year's time. By then, your wife Sarah will have borne a son."
11 Now Sarah was listening at the tent entrance behind him. Abraham and Sarah were old really old and Sarah was beyond the age of childbearing. 12 That's why Sarah laughed to herself, thinking, "After I'm so old and my husband is old, too, am I going to have sex?"
13 The LORD asked Abraham, "Why did Sarah laugh and think, "Am I really going to bear a child, since I'm so old?' 14 Is anything impossible for the LORD? At the time set for it, I will return to you about a year from now and Sarah will have a son."
15 But Sarah denied it. "I didn't laugh," she claimed, because she was afraid. The LORD replied, "No! You did laugh!"
