19 Then do to him what it was his purpose to do to his brother: and so put away the evil from among you. 20 And the rest of the people, hearing of it, will be full of fear, and never again do such evil among you. 21 Have no pity; let life be given for life, eye for eye, tooth for tooth, hand for hand, foot for foot.
Matthew Henry's Commentary on Deuteronomy 19:19-21
Commentary on Deuteronomy 19:15-21
(Read Deuteronomy 19:15-21)
Sentence should never be passed upon the testimony of one witness alone. A false witness should suffer the same punishment which he sought to have inflicted upon the person he accused. Nor could any law be more just. Let all Christians not only be cautious in bearing witness in public, but be careful not to join in private slanders; and let all whose consciences accuse them of crime, without delay flee for refuge to the hope set before them in Jesus Christ.
