Then the Lord said to Abraham, “Why did Sarah laugh and say, ‘Will I really have a child, now that I am old?’
So Sarah laughed to herself as she thought, “After I am worn out and my lord is old, will I now have this pleasure?”
Is anything too hard for the Lord? I will return to you at the appointed time next year, and Sarah will have a son.”
Sarah said, “God has brought me laughter, and everyone who hears about this will laugh with me.”
And she added, “Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.”
He did not need any testimony about mankind, for he knew what was in each person.
