Treasury of Scripture Knowledge
The Lord said to Abraham, "Why did Sarah laugh and say, 'Will I really have a child when I am old?'
Then Abraham bowed down with his face to the ground and laughed as he said to himself, "Can a son be born to a man who is a hundred years old? Can Sarah bear a child at the age of ninety?"
Sarah said, "God has made me laugh. Everyone who hears about this will laugh with me."
At that time we laughed loudly and shouted for joy. At that time the nations said, "The Lord has accomplished great things for these people."
Zechariah said to the angel, "How can I be sure of this? For I am an old man, and my wife is old as well."
By faith, even though Sarah herself was barren and he was too old, he received the ability to procreate, because he regarded the one who had given the promise to be trustworthy.
