Genesis 18:23-27

Abraham approached [the LORD] and said, “Will You really sweep away the righteous (those who do right) with the wicked (those who do evil)? Suppose there are fifty righteous [people] within the city; will You really sweep it away and not spare it for the sake of the fifty righteous who are in it? Far be it from You to do such a thing—to strike 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 do right [by executing just and righteous judgment]?” So the LORD said, “If I find within the city of Sodom fifty righteous [people], then I will spare the entire place for their sake.” Abraham answered, “Now behold, I who am but dust [in origin] and ashes have decided to speak to the Lord. [Gen 3:19; Job 30:19]
