John Calvin on Deuteronomy 13:9-11

9 But thou shalt surely kill him. He would not that every one should privately execute vengeance without a public trial; but he referred to the ordinary custom, that the witnesses should throw the first stone at condemned criminals, as we shall see elsewhere. For it was an admirable provision, that God would have those who had denounced the crime, to be the executors of its punishment, in order that they should be more cautious and moderate in giving their testimony. The reason, which is added at the end, “because he hath sought to thrust thee away from the Lord thy God, who brought thee out,” etc., again exaggerates the crime on the score of its ingratitude; which was detestable in proportion to the inestimable blessing of their deliverance. It was an act of gross wickedness to rebel against God after they had known Him; but it was still more gross to undervalue their Deliverer. Finally, the advantage and fruit of this severity is subjoined; for, whilst punishment was inflicted on one man’s crime, all others were inspired with terror; and thus the death of one is a wholesome discipline for all, in the way of example.

Deuteronomy 13

Deuteronomy 13:12-17

12. If thou shalt hear say in one of thy cities, which the Lord thy God hath given thee to dwell there, saying,

12. Si audieris de una urbium tuarum quas Jehova Deus tuus dat tibi ut habites ibi, aliquem dicen-tem:

13. Certain men, the children of Belial, are gone out from among you, and have withdrawn the inhabitants of their city, saying, Let us go and serve other gods, which ye have not known;

13. Egressi sunt quidam homines filii impietatis e medio tui, qui impulerunt habitatores urbis suae, dicendo, Eamus et colamus deos alienos quos non nostis.

14. Then shalt thou enquire, and make search, and ask diligently; and, behold, if it be truth, and the thing certain, that such abomination is wrought among you;

14. Tunc inquires, et investigabis diligenter: et siquidem veritas sit et rumor verus, quod facta sit abominatio ista in medio tui:

15. Thou shalt surely smite the inhabitants of that city with the edge of the sword, destroying it utterly, and all that is therein, and the cattle thereof, with the edge of the sword.

15. Percutiendo percuties habitatores urbis illius acie gladii, perdendo eam, et quicquid in ea fuerit, et jumenta ejus acie gladii.

16. And thou shalt gather all the spoil of it into the midst of the street thereof, and shalt burn with fire the city, and all the spoil thereof every whit, for the LORD thy God: and it shall be an heap for ever; it shall not be built again.

16. Atque omnia spolia ejus congregabis in medio plateae ejus, et combures igni urbem ipsam et omnia spolia ejus prorsus Jehovae Deo tuo, eritque tumulus perpetuus, non aedificabitur.

17. And there shall cleave nought of the cursed thing to thine hand: that the LORD may turn from the fierceness of his anger, and shew thee mercy, and have compassion upon thee, and multiply thee, as he hath sworn unto thy fathers;

17. Neque adhaerebit manui tuae quicquam de anathemate, ut avertatur Jehova ab ira furoris sui, et det tibi misericordias, misereaturque tui, ac te multiplicet quemadmodum juravit patribus tuis.
