Enticers to idolatry to be put to death. (1-5) Relations who entice to idolatry not to be spared. (6-11) Idolatrous cities not to be spared. (12-18)
Verses 1-5 Moses had cautioned against the peril that might arise from the Canaanites. Here he cautions against the rise of idolatry among themselves. It is needful for us to be well acquainted with the truths and precepts of the Bible; for we may expect to be proved by temptations of evil under the appearance of good, of error in the guise of truth; nor can any thing rightly oppose such temptations, but the plain, express testimony of God's word to the contrary. And it would be a proof of sincere affection for God, that, notwithstanding specious pretences, they should not be wrought upon the forsake God, and follow other gods to serve them.
Verses 6-11 It is the policy of Satan to try to lead us to evil by those whom we love, whom we least suspect of any ill design, and whom we are desirous to please, and apt to conform to. The enticement here is supposed to come from a brother or child, who are near by nature; from a wife or friend, who are near by choice, and are to us as our souls. But it is our duty to prefer God and religion, before the nearest and dearest friends we have in the world. We must not, to please our friends, break God's law. Thou shalt not consent to him, nor go with him, not for company, or curiosity, not to gain his affections. It is a general rule, If sinners entice thee, consent thou not, Pr. 1:10 . And we must not hinder the course of God's justice.
Verses 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!
In this chapter the Israelites are taught how to discern a false prophet, shun and punish him, De 13:1-5, what to do with enticers to idolatry, not only not to consent to them, but, without favour and affection to them, endeavour to bring them to just punishment, and be the first that should inflict it on them, De 13:6-11 and how to behave towards a city drawn into idolatry, as to inquire the truth of it; then make war against it; destroy all in it, men, women, children, and cattle; and burn the spoil of it, and suffer not anything at all belonging to it to cleave unto them, De 13:12-18.
