Genesis 18:11-14

Abraham and Sarah were very old. Since Sarah was past the age when women normally have children, she laughed to herself, “My husband and I are too old to have a baby.” Then the LORD said to Abraham, “Why did Sarah laugh? Why did she say, ‘I am too old to have a baby’? Is anything too hard for the LORD? No! I will return to you at the right time a year from now, and Sarah will have a son.”
