Genesis 18:23-33

And Abraham drew near, and said, Wilt thou consume the righteous with the wicked? Peradventure there are fifty righteous within the city: wilt thou consume and not spare the place for the fifty righteous that are therein? That be far from thee to do after this manner, to slay the righteous with the wicked, that so the righteous should be as the wicked; that be far from thee: shall not the Judge of all the earth do right? 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. And Jehovah went his way, as soon as he had left off communing with Abraham: and Abraham returned unto his place.
