The method of this song follows the method of the predictions in the foregoing chapter, and therefore, after the revolt of Israel from God, described in the foregoing verses, here follow immediately the resolves of divine Justice concerning them; we deceive ourselves if we think that God will be thus mocked by a foolish faithless people, that play fast and loose with him.

I.He had delighted in them, but now he would reject them with detestation and disdain, Deu 32:19. When the Lord saw their treachery, and folly, and base ingratitude, he abhorred them, he despised them, so some read it. Sin makes us odious in the sight of the holy God; and no sinners are so loathsome to him as those that he has called, and that have called themselves, his sons and his daughters, and yet have been provoking to him. Note, The nearer any are to God in profession the more noisome are they to him if they are defiled in a sinful way, Psa 106:39, Psa 106:40.

II.He had given them the tokens of his presence with them and his favour to them; but now he would withdraw and hide his face from them, Deu 32:20. His hiding his face signifies his great displeasure; they had turned their back upon God, and now God would turn his back upon them (compare Jer 18:17 with Jer 2:27); but here it denotes also the slowness of God's proceedings against them in a way of judgment. They began in their apostasy with omissions of good, and so proceeded to commissions of evil. In like manner God will first suspend his favours, and let them see what the issue of that will be, what a friend they lose when they provoke God to depart, and will try whether this will bring them to repentance. Thus we find God hiding himself, as it were, in expectation of the event, Isa 57:17. To justify himself in leaving them he shows that they were such as there was no dealing with; for, 1. They were froward and a people that could not be pleased, or obstinate in sin, and that could not be convinced and reclaimed. 2. They were faithless, and a people that could not be trusted. When he saved them, and took them into covenant, he said, Surely they are children that will not lie (Isa 63:8); but when they proved otherwise, children in whom is no faith, they deserved to be abandoned, and that the God of truth should have no more to do with them.

III.He had done every thing to make them easy and to please them, but now he would do that against them which should be most vexatious to them. The punishment here answers the sin, Deu 32:21. 1. They had provoked God with despicable deities which were not gods at all, but vanities, creatures of their own imagination, that could not pretend either to merit or to repay the respects of their worshippers; the more vain and vile the gods were after which they went a whoring the greater was the offence to that great and good God whom they set them up in competition with and contradiction to. This put two great evils into their idolatry, Jer 2:13. 2. God would therefore plague them with despicable enemies, that were worthless, weak, and inconsiderable, and not deserving the name of a people, which was a great mortification to them, and aggravated the oppressions they groaned under The more base the people were that tyrannised over them the more barbarous they would be (none so insolent as a beggar on horseback), besides that it would be infamous to Israel, who had so often triumphed over great and mighty nations, to be themselves trampled upon by the weak and foolish, and to come under the curse of Canaan, who was to be a servant of servants. But God can make the weakest instrument a scourge to the strongest sinner; and those that by sin insult their might Creator are justly insulted by the meanest of their fellow-creatures. This was remarkably fulfilled in the days of the judges, when they were sometimes oppressed by the very Canaanites themselves, whom they had subdued, Jdg 4:2. But the apostle applies it to the conversion of the Gentiles, who had been a people not in covenant with God, and foolish in divine things, yet were brought into the church, sorely to the grief of the Jews, who upon all occasions showed a great indignation at it, which was both their sin and their punishment, as envy always is, Rom 10:19.

IV.He had planted them in a good land, and replenished them with all good things; but now he would strip them of all their comforts, and bring them to ruin. The judgments threatened are very terrible, Deu 32:22-25. 1. The fire of God's anger shall consume them, Deu 32:22. Are they proud of their plenty? It shall burn up the increase of the earth. Are they confident of their strength? It shall destroy the very foundations of their mountains: there is no fence against the judgments of God when they come with commission to lay all waste. It shall burn to the lowest hell, that is, it shall bring them to the very depth of misery in this world, which yet would be but a faint resemblance of the complete and endless misery of sinners in the other world. The damnation of hell (as our Saviour calls it) is the fire of God's anger, fastening upon the guilty conscience of a sinner, to its inexpressible and everlasting torment, Isa 30:33. 2. The arrows of God's judgments shall be spent upon them, till his quiver is quite exhausted, Deu 32:23. The judgments of God, like arrows, fly swiftly (Psa 64:7), reaching those at a distance who flatter themselves with hopes of escaping them, Psa 21:8, Psa 21:12. They come from an unseen hand, but wound mortally, for God never misses his mark, Kg1 22:34. The particular judgments here threatened are, (1.) Famine: they shall be burnt, or parched, with hunger. (2.) Pestilence and other diseases, here called burning heat and bitter destruction. (3.) The insults of the inferior creatures: the teeth of beasts and the poison of serpents, Deu 32:24. (4.) War and the fatal consequences of it, Deu 32:25. [1.] Perpetual frights. When the sword is without, there cannot but be terror within. Co2 7:5, Without were fightings, within were fears. Those who cast off the fear of God are justly exposed to the fear of enemies. [2.] Universal deaths. The sword of the Lord, when it is sent to lay all waste, will destroy without distinction; neither the strength of the young man nor the beauty of the virgin, neither the innocency of the suckling nor the gravity or infirmity of the man of gray hairs, will be their security from the sword when it devours one as well as another. Such devastation does war make, especially when it is pushed on by men as ravenous as wild beasts and as venomous as serpents, Deu 32:24. See here what mischief sin does, and reckon those fools that make a mock at it.

They have moved me to jealousy with that which is not God,.... With a false messiah; for after the death of Jesus, the true Messiah, God as well as man, many false Christs arose, as he predicted, and were received for a time, who were mere men, and deceivers; and their now vainly expected messiah, or whom they look for, according to their own sense of him, is no other than a mere creature, and not God: or with the idol of their own righteousness; which, as an idol is nothing in the world, that is, nothing in the business of justification, and put in the room of Christ highly provokes the Lord to jealousy:

they have provoked me to anger with their vanities; such were their false Christs they in vain trusted in, and such the idol of their own righteousness they set up, but could not make to stand; and such were the traditions of their elders; they put upon an equality with, or above the word of God; all which stirred up the wrath and anger of God against them:

and I will move them to jealousy with those which are not a people: this is not to be understood of any particular nation, but of the Gentiles in general, and of God's elect among them, and of the calling of them; which would be provoking to the Jews, as the Apostle Paul has taught us to understand it, Rom 10:19. These were not the people of God, or not my people, as he says Rom 9:25; In some sense indeed they were his people, being chosen by him, and taken into covenant with him; for he is God not of the Jews only, but of the Gentiles also; and those were given to Christ as his people, and are his other sheep which were not of the Jewish fold; and who were redeemed by him to be a peculiar people out of every kindred, tongue, people, and nation, all which was before their calling: yet, in another sense they were not his people; they were without any spiritual privileges, the word and ordinances, without the knowledge of God and Christ, without communion with them; they were not a people near unto the Lord, he had not laid hold on and formed them for himself in regeneration and conversion; they were not reckoned the people of God, nor called so, and especially by the Jews, who accounted themselves to be the only people of God; see Eph 2:11,

I will provoke them to anger with a foolish nation; either the Romans in particular are meant, so called because of their gross idolatry, to which they were addicted, who otherwise in their political affairs were a wise and understanding people; to these Judea became a province, and were subject to tribute; and by the exactions of the Romans, and their ill usage of them, they were provoked to rise against them, which issued in their ruin: or rather the Gentiles in general, who might be called foolish because of their superstition and idolatry, ignorance, and blindness in religious matters, and especially were so in the account of the Jews; and the elect of God among them in particular, who in their state of unregeneracy were foolish, as all unregenerate men are; both their principles and practices were foolish, and they were the foolish things of the Gentile world that God chose and called: and the calling of them was exceedingly provoking to the Jews; which was as if a man, moved to jealousy by the behaviour of his wife, should strip her of her ornaments and jewels, and reject her as his wife; and take another before her eyes of mean estate, and marry her, and put her ornaments on her, to which the allusion is; for the Lord, being moved to jealousy by the conduct of the Jewish nation towards him, rejected them from being his people, and stripped them of all their privileges, civil and religious, and took the Gentiles in the room of them, and so in just retaliation moved them to jealousy and wrath. It was displeasing to the carnal Jews to hear of the prophecies of the calling of the Gentiles, Rom 10:20; and the first display of grace to them was resented even by believing Jews themselves at first, Act 11:2. The anger of the Scribes and Pharisees on this account is thought by some to be hinted at in the parable of the two sons, Luk 15:27. The Jews were offended with Christ for eating with publicans, the Roman tax gatherers, and were greatly displeased when he told them the kingdom of God would be taken from them, and given to another nation, Mat 9:10 Mat 21:43. Their rage and envy were very great when the Gospel was first preached to the Gentiles, Act 13:41; and there is such an extraordinary instance of their spite and malice to the Gentiles, and of their jealousy and anger they were moved unto, as is not to be paralleled, Th1 2:15.

They sacrificed unto devils--(See on Lev 17:7).
