Genesis 18:25-32

25That be far from thee to do after this manner, to slay the righteous with the wicked: and that the righteous should be as the wicked, that be far from thee: Shall not the Judge of all the earth do right?

26And Yhwh said, If I find in Sodom fifty righteous within the city, then I will spare all the place for their sakes.

27And Abraham answered and said, Behold now, I have taken upon me to speak unto the Lord, which am but dust and ashes:

28Peradventure there shall lack five of the fifty righteous: wilt thou destroy all the city for lack of five? And he said, If I find there forty and five, I will not destroy it.

29And he spake unto him yet again, and said, Peradventure there shall be forty found there. And he said, I will not do it for forty’s sake.

30And he said unto him, 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.

31And 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.

32And 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 ten’s sake.
