And they provoked God to anger. The prophet once more informs us, that they had been put upon their guard by another plague, in order that it might appear that God had always a strict regard for his own glory, in chastising the people; but as they were not bettered by these plagues, these chastisements were fruitless. Having formerly stated, that God's wrath had been appeased by the prayers of Moses, he now says, that the plague had been arrested or ceased by means of the kind interposition of Phinehas. Some render the word phll, pillel, to pray; but the other rendering, to execute justice, is more in accordance with the context; namely, that by his zeal in executing justice upon the profligates, he turned away God's vengeance from the Israelites. He stood up therefore, that is, he rose up or interposed, when all others maintained a careless indifference. As the Jews were sensible that it was by the kind intervention of one man that the plague was now healed, their obstinacy was the less excusable in not even then ceasing to sin. We must not forget that all these things are addressed to us. For when God from time to time chastises us, and calls upon us to repent by setting before us the example of others, how few profit by his corrections! Moreover, it deserves to be noticed, that the plague ceased at the very time when Phinehas executed justice. From this we may learn, that the most effectual way to quench the fire of God's anger, is when the sinner willingly sits in judgment upon himself for the punishment of his own transgressions; as Paul says, 1-Corinthians 11:31, "If we would judge ourselves, verily we would not be judged of the Lord." And surely God confers no small honor upon us, in placing the punishment of our sins within our reach. At the same time, it must be observed, that on that occasion the plague ceased in consequence of the punishment of a single person, because the people then shrunk from the abominable wickedness to which they had been addicted.

Thus they provoked him to anger with their inventions - The word rendered "inventions" means properly "works; deeds;" then it is used in the sense of "evil" deeds, crimes.
And the plague brake in upon them - See Numbers 25:8-9. No less than twenty-four thousand fell in the plague. Numbers 25:9.

Thus they (q) provoked [him] to anger with their inventions: and the plague brake in upon them.
(q) Signifying that whatever man invents of himself to serve God by, is detestable and provokes his anger.

Thus they provoked him to anger with their inventions,.... Sin is an invention of man's: when our first parents sinned, they found out many inventions; and their posterity ever since have been inventors of evil things; and man's invention is very quick at that work. All false doctrine and false worship are of men's finding out; all idolatrous practices are their inventions, and which are here intended; see Psalm 106:39. And these are very provoking to God, who is jealous of his glory, and which is taken from him hereby; and even when he forgives such sins of men, he takes vengeance on their inventions, as in this case, Psalm 99:8. For it follows:
and the plague brake in upon them: like an inundation of water, and carried off four and twenty thousand persons, Numbers 25:9.

provoked--excited grief and indignation (Psalm 6:7; Psalm 78:58).
