Genesis 18:23-27

Far be it from You to do such a thing, to kill the righteous with the wicked, so that the righteous and the wicked are treated alike. Far be it from You! Shall not the Judge of all the earth deal justly?”

And Abraham replied, “Now behold, I have ventured to speak to the Lord, although I am only dust and ashes.
