Genesis 18:10-12

New Century Version

¹⁰ Then the Lord said, “I will certainly return to you about this time a year from now. At that time your wife Sarah will have a son.”

Sarah was listening at the entrance of the tent which was behind him. ¹¹ Abraham and Sarah were very old. Since Sarah was past the age when women normally have children, ¹² she laughed to herself, “My husband and I are too old to have a baby.”
