'According to What He Has Done' in the Bible

If you say, "Look here, we didn't know about this," doesn't God, who examines motives, discern it? Doesn't the one who guards your soul know about it? Won't he repay each person according to what he has done?

Do not say, "I will do to him just as he has done to me; I will pay him back according to what he has done."
