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!When thou shalt hearken to the voice of the Lord thy God,.... Not only in this case, but in all others:

to keep all his commandments which I command thee this day: the repetition of which he made unto them, and enjoined the observance of them in the name of the Lord:

to do that which is right in the eyes of the Lord thy God; which they would do, if they kept the commandments of the Lord, which are holy, just, and good, and must be right in his sight because commanded by him.
