Genesis 18:26-32

26And Jehovah said, If I find at Sodom fifty righteous within the city, then I will forgive all the place for their sakes.

27And Abraham answered and said, Behold now, I have ventured to speak unto the Lord; I, who am dust and ashes.

28Perhaps there may want five of the fifty righteous: wilt thou destroy all the city on account of the five? And he said, If I shall find forty-five there, I will not destroy [it].

29And he continued yet to speak with him, and said, Perhaps there may be forty found there. And he said, I will not do it for the forty's sake.

30And he said, Oh, let not the Lord be angry that I speak! Perhaps there may be thirty found there. And he said, I will not do it if I find thirty there.

31And he said, Behold now, I have ventured to speak with the Lord. Perhaps there may be twenty found there. And he said, I will not destroy [it] for the twenty's sake.

32And he said, Oh, let not the Lord be angry, that I speak yet but this time! Perhaps there may be ten found there. And he said, I will not destroy [it] for the ten's sake.
