Magistracy and ministry are two divine institutions of admirable use for the support and advancement of the kingdom of God among men. Laws concerning the former we had in the close of the foregoing chapter, directions are in this given concerning the latter. Land-marks are here set between the estates of the priests and those of the people. I. Care is taken that the priests entangle not themselves with the affairs of this life, nor enrich themselves with the wealth of this world; they have better things to mind. They shall have no part nor inheritance with Israel, that is, no share either in the spoils taken in war or in the land that was to be divided by lot, Deu 18:1. Their warfare and husbandry are both spiritual, and enough to fill their hands both with work and profit and to content them. The Lord is their inheritance, Deu 18:2. Note, Those that have God for their inheritance, according to the new covenant, should not be greedy of great things in the world, neither gripe what they have nor grasp at more, but look upon all present things with the indifference which becomes those that believe God to be all-sufficient. II. Care is likewise taken that they want not any of the comforts and conveniences of this life. Though God, who is a Spirit, is their inheritance, it does not therefore follow that they must live upon the air; no, 1. The people must provide for them. They must have their due from the people, Deu 18:3. Their maintenance must not depend upon the generosity of the people, but they must be by law entitled to it. He that is taught in the word ought in justice to communicate to him that teaches him; and he that has the benefit of solemn religious assemblies ought to contribute to the comfortable support of those that preside in such assemblies. (1.) The priests who in their courses served at the altar had their share of the sacrifices, namely, the peace-offerings, that were brought while they were in waiting: besides the breast and shoulder, which were appointed them before (Lev 7:32-34), the cheeks and maw are here ordered to be given them; so far was the law from diminishing what was already granted that it gave them an augmentation (2.) The first-fruits which arose within such a precinct were brought in, as it should seem, to the priests that resided among them, for their maintenance in the country; the first of their corn and wine for food, and the first of their fleece for clothing (Deu 18:4); for the priests who were employed to teach others ought themselves to learn, having food and raiment, to be therewith content. The first-fruits were devoted to God, and he constituted the priests his receivers; and if God reckons what is, in general, given to the poor, lent to him, to be repaid with interest, much more what is, in particular, given to the poor, lent to him, to be repaid with interest, much more what is, in particular, given to poor ministers. There is a good reason given for this constant charge upon their estates (Deu 18:5), because the Levites were chosen of God, and his choice must be owned and countenanced, and those honoured by us whom he honours; and because they stood to minister, and ought to be recompensed for their attendance and labour, especially since it was in the name of the Lord, by his warrant, in his service, and for his praise, and this charge entailed upon their seed for ever; those who were thus engaged and thus employed ought to have all due encouragement given them, as some of the most needful useful members of their commonwealth. 2. The priests must not themselves stand in one another's light. If a priest that by the law was obliged to serve at the altar only in his turn, and was paid for that, should, out of his great affection to the sanctuary, devote himself to a constant attendance there, and quit the ease and pleasure of the city in which he had his lot for the satisfaction of serving the altar, the priests whose turn it was to attend must admit him both to join in the work and to share in the wages, and not grudge him either the honour of the one or the profit of the other, though it might seem to break in upon them, Deu 18:6-8. Note, A hearty pious zeal to serve God and his church, though it may a little encroach upon a settled order, and there may be somewhat in it that looks irregular, yet ought to be gratified and not discouraged. He that appears to have a hearty affection to the sanctuary, and loves dearly to be employed in the service of it, in God's name let him minister; he shall be as welcome to God as the Levites whose course it was to minister, and should be so to them. The settling of the courses was intended rather to secure those to the work that were not willing to do so much than to exclude any that were willing to do more. And he that thus serves as a volunteer shall have as good pay as the pressed men, besides that which comes of the sale of his patrimony. The church of Rome obliges those who leave their estates to go into a monastery to bring the produce of their estates with them into the common stock of the monastery, for gain is their godliness; but here it is ordered that the pious devotee should reserve to himself the produce of his patrimony, for religion and the ministry were never appointed of God, however they have been abused by men, to serve a secular interest.

One would not think there had been so much need as it seems there was to arm the people of Israel against the infection of the idolatrous customs of the Canaanites. Was it possible that a people so blessed with divine institutions should ever admit the brutish and barbarous inventions of men and devils? Were they in any danger of making those their tutors and directors in religion whom God had made their captives and tributaries? It seems they were in danger, and therefore, after many similar cautions, they are here charged not to do after the abominations of those nations, Deu 18:9. I. Some particulars are specified; as, 1. The consecrating of their children to Moloch, an idol that represented the sun, by making them to pass through the fire, and sometimes consuming them as sacrifices in the fire, Deu 18:10. See the law against this before, Lev 18:21. 2. Using arts of divination, to get the unnecessary knowledge of things to come, enchantments, witchcrafts, charms, etc., by which the power and knowledge peculiar to God were attributed to the devil, to the great reproach both of God's counsels and of his providence, Deu 18:10, Deu 18:11. one would wonder that such arts and works of darkness, so senseless and absurd, so impious and profane, could be found in a country where divine revelation shone so clearly; yet we find remains of them even where Christ's holy religion is known and professed; such are the powers and policies of the rulers of the darkness of this world. But let those give heed to fortune-tellers, or go to wizards for the discovery of things secret, that use spells for the cure of diseases, are in any league or acquaintance with familiar spirits, or form a confederacy with those that are - let them know that they can have no fellowship with God while thus they have fellowship with devils. It is amazing to think that there should by any pretenders of this kind in such a land and day of light as we live in. II. Some reasons are given against their conformity to the customs of the Gentiles. 1. Because it would make them abominable to God. The things themselves being hateful to him, those that do them are an abomination; and miserable is that creature that has become odious to its Creator, Deu 18:12. See the malignity and mischievousness of sin; that must needs be an evil thing indeed which provokes the God of mercy to detest the work of his own hands. 2. Because these abominable practices had been the ruin of the Canaanites, of which ruin they were not only the witnesses but the instruments. It would be the most inexcusable folly, as well as the most unpardonable impiety, for them to practise themselves those very things for which they had been employed so severely to chastise others. Did the land spue out the abominations of the Canaanites, and shall Israel lick up the vomit? 3. Because they were better taught, Deu 18:13, Deu 18:14. It is an argument like that of the apostle against Christians walking as the Gentiles walked (Eph 4:17, Eph 4:18, Eph 4:20): You have not so learned Christ. "It is true these nations, whom God gave up to their own hearts' lusts, and suffered to walk in their own ways (Act 14:16), did thus corrupt themselves; but thou art not thus abandoned by the grace of God: the Lord thy God had not suffered thee to do so; thou art instructed in divine things, and hast fair warning given thee of the evil of those practices; and therefore, whatever others do, it is expected that thou shouldest be perfect with the Lord thy God," that is, "that thou shouldest give divine honours to him, to him only, and to no other, and not mix any of the superstitious customs of the heathen with his institutions." One of the Chaldee paraphrasts here takes notice of God's furnishing them with the oracle of urim and thummim, as a preservative from all unlawful arts of divination. Those were fools indeed who would go to consult the father of lies when they had such a ready way of consulting the God of truth.
