Genesis 18:23-25

23Abraham came closer and asked, “Are you really going to sweep away the innocent with the guilty?

24What if there are 50 innocent people in the city? Are you really going to sweep them away? Won’t you spare that place for the sake of the 50 innocent people who are in it?

25It would be unthinkable for you to do such a thing, to treat the innocent and the guilty alike and to kill the innocent with the guilty. That would be unthinkable! Won’t the judge of the whole earth do what is fair?”
