Genesis 18:26-32

And Jehovah said, If I find in Sodom fifty righteous within the city, then I will spare all the place for their sake. And Abraham answered and said, Behold now, I have taken upon me to speak unto the Lord, who am but dust and ashes: peradventure there shall lack five of the fifty righteous: wilt thou destroy all the city for lack of five? And he said, I will not destroy it, if I find there forty and five. And he spake unto him yet again, and said, Peradventure there shall be forty found there. And he said, I will not do it for the forty’s sake. And he said, Oh let not the Lord be angry, and I will speak: peradventure there shall thirty be found there. And he said, I will not do it, if I find thirty there. 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 the twenty’s sake. And he said, Oh let not the Lord be angry, and I will speak yet but this once: peradventure ten shall be found there. And he said, I will not destroy it for the ten’s sake.
