Deuteronomy 19:19ESV·traditional attribution

then you shall do to him as he had meant to do to his brother. So you shall purge the evil from your midst.

Matthew Henry Presbyterian @wholebiblehenry

Here is a statute for the preventing of frauds and perjuries; for the divine law takes care of men's rights and properties, and has made a hedge about them. Such a friend is it to human society and men's civil interest. I. A law against frauds, Deu 19:14. 1.

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. Deuteronomy 19:21

PUNISHMENT OF A FALSE WITNESS. (Deu 19:16-21) 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 Exo 21:23; see also Lev 24:20). Next: Deuteronomy Chapter 20
