Genesis Chapter 18 Verse 20And the LORD said, Because the cry of Sodom and Gomorrah is great, and because their sin is very grievous;

And he said, I will certainly return unto thee according to the time of life; and, lo, Sarah thy wife shall have a son. And Sarah heard [it] in the tent door, which [was] behind him.

Now Abraham and Sarah [were] old [and] well stricken in age; [and] it ceased to be with Sarah after the manner of women.

Therefore Sarah laughed within herself, saying, After I am waxed old shall I have pleasure, my lord being old also?

And the LORD said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, which am old?

Is any thing too hard for the LORD? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son.

Then Sarah denied, saying, I laughed not; for she was afraid. And he said, Nay; but thou didst laugh.

And the men rose up from thence, and looked toward Sodom: and Abraham went with them to bring them on the way.

And the LORD said, Shall I hide from Abraham that thing which I do;

Seeing that Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him?

For I know him, that he will command his children and his household after him, and they shall keep the way of the LORD, to do justice and judgment; that the LORD may bring upon Abraham that which he hath spoken of him.

I will go down now, and see whether they have done altogether according to the cry of it, which is come unto me; and if not, I will know.

And the men turned their faces from thence, and went toward Sodom: but Abraham stood yet before the LORD.

And Abraham drew near, and said, Wilt thou also destroy the righteous with the wicked?

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

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?

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

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

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].

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.

And 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.
