Genesis 18:22

19 For I have known him, to the end that he may command his children and his household after him, that they may keep the way of the LORD, to do righteousness and justice; to the end that the LORD may bring on Abraham that which he has spoken of him.”

20 The LORD said, “Because the cry of Sodom and Gomorrah is great, and because their sin is very grievous,

21 I will go down now, and see whether their deeds are as bad as the reports which have come to me. If not, I will know.”

22 The men turned from there, and went toward Sodom, but Abraham stood yet before the LORD.

23 Abraham came near, and said, “Will you consume the righteous with the wicked?

24 What if there are fifty righteous within the city? Will you consume and not spare the place for the fifty righteous who are in it?

25 May it be far from you to do things like that, to kill the righteous with the wicked, so that the righteous should be like the wicked. May that be far from you. Shouldn’t the Judge of all the earth do right?”
