Deuteronomy 19
18 Ref And the judges will have the question looked into with care: and if the witness is seen to be false and to have made a false statement against his brother,
19 Ref Then do to him what it was his purpose to do to his brother: and so put away the evil from among you.
20 Ref And the rest of the people, hearing of it, will be full of fear, and never again do such evil among you.
