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.See the marginal references. De 19:16-21. Punishment of a False Witness.

16-21. But if convicted of perjury, it will be sufficient for his own condemnation, and his punishment shall be exactly the same as would have overtaken the object of his malignant prosecution. (See on [158]Ex 21:23; see also Le 24:20).

Those which remain, i.e. the rest of the people. See Deu 13:11 17:13.

And those which remain shall hear, and fear,.... Those which survive the false witness shall hear of the punishment inflicted on him, and fear to commit the like sin, lest they should be punished in like manner. And those which remain shall hear, and fear, and shall henceforth commit no more any such evil among you.
