16 If a malicious witness rises against any man to accuse him of wrongdoing, 17 then both parties to the dispute shall appear before the Lord, before the priests and the judges who are in office in those days; 18 the judges shall inquire diligently, and if the witness is a false witness and has accused his brother falsely, 19 then you shall do to him as he had meant to do to his brother; so you shall purge the evil from the midst of you. 20 And the rest shall hear, and fear, and shall never again commit any such evil among you. 21 Your eye shall not pity; it shall be life for life, eye for eye, tooth for tooth, hand for hand, foot for foot.
Matthew Henry's Commentary on Deuteronomy 19:16-21
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.
