Genesis 18:26 KJV

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

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 the LORD 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.
