18 and the judges have searched diligently, and lo, the witness 'is' a false witness, a falsehood he hath testified against his brother: 19 'Then ye have done to him as he devised to do to his brother, and thou hast put away the evil thing out of thy midst, 20 and those who are left do hear and fear, and add not to do any more according to this evil thing in thy midst;
Matthew Henry's Commentary on Deuteronomy 19:18-20
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.
