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 you must certainly put to the sword all who live in that town. You must destroy it completely,
15 you shall surely put the inhabitants of that city to the sword, devoting it to destruction,
15 you must execute the citizens of that town. Kill them, setting that city apart for holy destruction: the city and everything in it including its animals.
15 you shall surely strike the inhabitants of that city with the edge of the sword--utterly destroying it, all that is in it and its livestock, with the edge of the sword.
15 you must attack that town and completely destroy all its inhabitants, as well as all the livestock.
Matthew Henry's Commentary on Deuteronomy 13:15
Commentary on Deuteronomy 13:12-18
(Read Deuteronomy 13:12-18)
Here is the case of a city revolting from the God of Israel, and serving other gods. The crime is supposed to be committed by one of the cities of Israel. Even when they were ordered to preserve their religion by force, yet they were not allowed to bring others to it by fire and sword. Spiritual judgments under the Christian dispensation are more terrible than the execution of criminals; we have not less cause than the Israelites had, to fear the Divine wrath. Let us then fear the spiritual idolatry of covetousness, and the love of worldly pleasure; and be careful not to countenance them in our families, by our example or by the education of our children. May the Lord write his law and truth in our hearts, there set up his throne, and shed abroad his love!
