For the violent man is brought to nought. He states more clearly what we have already mentioned in the former verse, namely, that the restoration of the Church consists in this, that the Lord raises up those who are cast down, and has compassion on the poor. But that purification of the Church, of which we have already spoken, is first necessary; for so long as the Lord does not execute his judgment against the wicked, and the bad are mixed with the good, so as even to hold the highest place in the Church, everything is soiled and corrupted, God is not worshipped or feared, and even godliness is trampled under feet. When therefore the ungodly are removed or subdued, the Church is restored to its splendour, and the godly, freed from distresses and calamities, leap for joy. First, he calls them rytsym, (gnaritzim,) "violent." There are various interpretations of this word; but I think that the Prophet distinguishes between those who are openly wicked, and have no shame, and those who have some appearance of goodness, and yet are not better than others, for they mock at God in their hearts. But perhaps by the two adjectives, "violent" and "scorners," he describes the same persons; because, like robbers among men, they seize, oppress, treat with cruelty, and commit every kind of outrage, and yet are not withheld by any fear of God, because they regard religion as a fable. And they who hastened early to iniquity. Under this class he includes other crimes. He speaks not of the Chaldeans or Assyrians, but of those who wished to be reckoned in the number of the godly, and boasted of being the seed of Abraham.

For the terrible one - The violent one (עריץ ‛ârı̂yts), the oppressor, who had exercised cruelty over them. This, I suppose, refers to the haughty among the Jews themselves; to those who held offices of power, and who abused them to oppress the poor and needy.
And the scorner - (see Isaiah 28:14, Isaiah 28:22).
Is consumed - Shall be entirely destroyed.
And all that watch for iniquity - That is, who anxiously seek for opportunities to commit iniquity.

For the terrible one is brought to nought,.... Who before was so to the people of God; meaning not Sennacherib king of Assyria, but some formidable enemy or enemies under the Gospel dispensation; as the Scribes and Pharisees, and the Jewish sanhedrim; who were "violent" (c), as it may be rendered, violent persecutors of the followers of Christ, the meek and poor before described; who were brought to nought, and their power ceased at the destruction of Jerusalem; and the Roman emperor, with all subordinate rulers and governors in the empire, who harassed the Christians in a terrible manner, but were at last brought to nought by Constantine, and their persecution ceased; and the Romish antichrist, who has been so terrible, that none could or dared oppose him; he in a little time will be brought to nought, and cease to be. The Septuagint version renders it, "the wicked one faileth"; and uses the same word (d), by which antichrist is described, 2-Thessalonians 2:8 also Satan, that terrible enemy of the saints, shall be brought to nought; first bound for a thousand years; and afterwards, being loosed, shall be taken again, and cast into the lake of fire; all which will be matter of joy to the meek and lowly:
and the scorner is consumed; the same as before, only represented under a different character; the Jew, that mocked at Christ, because of his meanness, and that of his followers, that scoffed at his doctrines and miracles; and the Gentile, that derided his cross, and the preaching of it; and antichrist, whose mouth is full of blasphemies against God, and his tabernacle, and them that dwell in it:
and all that watch for iniquity are cut off; that cannot sleep unless they commit it, and seek for and take all opportunities of doing it; or watch for iniquity in others, in Christ, and the professors of his religion; or for anything they could call so, that they might have something to accuse them of, and charge them with, and a pretence to proceed against them in colour of law and justice: which has been the practice of Jews, Pagans, and Papists.
(c) "violentus", Junius & Tremellius, Piscator, Cocceius. (d)

terrible--namely, the persecutors among the Jewish nobles.
scorner-- (Isaiah 28:14, Isaiah 28:22).
watch for--not only commit iniquity, but watch for opportunities of committing it, and make it their whole study (see Micah 2:1; Matthew 26:59; Matthew 27:1).

That watch - That early and diligently apply themselves to the practice of wickedness.
