| Gill's Exposition of the Entire Bible A violent man enticeth his neighbour,.... As false teachers do, who are grievous wolves, not sparing the flock, and who by good words and fair speeches deceive the heart of the simple; and as the man of sin, that has shed the blood of the saints, and been drunk with the same, deceives with his miracles and sorceries them that dwell on the earth; and leadeth him into the way that is not good; yea, into one that is very bad; so far are false teachers from leading their neighbours into the good old way of truth and righteousness, that they lead them into pernicious ways, by whom the way; of truth is spoken evil of; they lead them into a ditch, and into destruction hereafter; as does the man of sin and violence his followers.
Keil and Delitzsch Biblical Commentary on the Old Testament29 A man of violence enticeth his neighbour, And leadeth him in a way which is not good. Cf. Genesis 4:8. The subject is not moral enticement, but enticement to some place or situation which facilitates to the violent man the carrying out of his violent purpose (misdemeanour, robbery, extortion, murder). חמס (here with אישׁ at Proverbs 3:31) is the injustice of club-law, the conduct of him who puts his superior power in godless rudeness in the place of God, Habakkuk 1:11, cf. Job 12:6. "A way not good" (cf. Psalm 36:5) is the contradictory contrast of the good way: one altogether evil and destructive.
Geneva Study BibleA violent man enticeth his neighbour, and leadeth him into the way that is not good.
Jamieson-Fausset-Brown Bible Commentary29. violent man-or, "man of mischief" (Pr 3:31). enticeth-(Pr 1:10).
Matthew Henry's Concise Commentary16:27,28. Ungodly men bestow more pains to do mischief than would be needful to do good. The whisperer separates friends: what a hateful, but how common a character! 29,30. Some do all the mischief they can by force and violence, and are blind to the result. 31. Old people especially should be found in the way of religion and godliness. 32. To overcome our own passions, requires more steady management, than obtaining victory over an enemy. 33. All the disposal of Providence concerning our affairs, we must look upon to be the determining what we referred to God; and we must be reconciled to them accordingly. Blessed are those that give themselves up to the will of God; for he knows what is good for them.
Matthew Henry's Whole Bible CommentaryVerses 29-30 Here is another sort of evil men described to us, that we may neither do like them, nor have any thing to do with them. 1. Such as (like Satan) do all the mischief they can by force and violence, as roaring lions, and not only by fraud and insinuation, as subtle serpents: They are violent men, that do all by rapine and oppression, that shut their eyes, meditating with the closest intention and application of mind to devise froward things, to contrive how they may do the greatest mischief to their neighbour, to do it effectually and yet securely to themselves; and then moving their lips, giving the word of command to their agents, they bring the evil to pass, and accomplish the wicked device, biting his lips (so some read it) for vexation. When the wicked plots against the just he gnasheth upon him with his teeth. 2. Such as (like Satan still) do all they can to entice and draw in others to join with them in doing mischief, leading them in a way that is not good, that is not honest, nor honourable, nor safe, but offensive to God, and which will be in the end pernicious to the sinner. Thus he aims to ruin some in this world by bringing them into trouble, and others in the other world by bringing them into sin. |
