Genesis 18:31

He said , Behold , I have undertaken to speak to the Lord . Suppose twenty are found there . He answered , For the sake of twenty I will not destroy it.

Abraham said, “Now that I have been so bold as to speak to the Lord, what if only twenty can be found there?” He said, “For the sake of twenty, I will not destroy it.”

And he said, Behold now, I have taken upon me to speak unto the Lord : Peradventure there shall be twenty found there. And he said, I will not destroy it for twenty's sake.
