Genesis 18:24-29
King James Version
24 Peradventure there be fifty righteous within the city: wilt thou also destroy and not spare the place for the fifty righteous that are therein?

25 That 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?

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 upon me to speak unto the Lord, which am but dust and ashes:

28 Peradventure 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.

29 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 forty's sake.Revised bible quote@ 31:35

King James Version
9 The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
