Genesis 18:24

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.”

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

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

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?”

The LORD said, “If I find in Sodom fifty righteous within the city, then I will spare the whole place for their sake.”

Abraham answered, “See now, I have taken it on myself to speak to the Lord, although I am dust and ashes.
