Genesis 18:24-32

24 Peradventure there be fifty righteous within the city: will you also destroy and not spare the place for the fifty righteous that are therein?

25 That be far from you 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 you: Shall not the Judge of all the earth do right?

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

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

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

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

30 And he said to 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.

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

32 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 ten's sake.
