Genesis 18:10-12

10Then one of the men said, ‘I will certainly return to you at about this time next year. At that time Sarah, your wife, will have a son!’ Sarah was listening to all this. She was at the door of the tent, near to where they were talking.

11Abraham and Sarah were now very old. Sarah was past the age when she could give birth to a child.

12So Sarah laughed to herself. She thought, ‘I have become old and weak. My husband is also old. I will never have a baby and be happy like that.’
