Matthew Henry commentary on Proverbs 21:13-16
Embedded KJV/source Scripture
15 It is joy to the just to do judgment: but destruction shall be to the workers of iniquity.
Note, 1. It is a pleasure and satisfaction to good men both to see justice administered by the government they live under, right taking place and iniquity suppressed, and also to practise it themselves, according as their sphere is. They not only do justice, but do it with pleasure, not only for fear of shame, but for love of virtue. 2. It is a terror to wicked men to see the laws put in execution against vice and profaneness. It is destruction to them; as it is also a vexation to them to be forced, either for the support of their credit or for fear of punishment, to do judgment themselves. Or, if we take it as we read it, the meaning is, There is true pleasure in the practice of religion, but certain destruction at the end of all vicious courses.

16 The man that wandereth out of the way of understanding shall remain in the congregation of the dead.
Here is, 1. The sinner upon his ramble: He wanders out of the way of understanding, and when once he has left that good way he wanders endlessly. The way of religion is the way of understanding; those that are not truly pious are not truly intelligent; those that wander out of this way break the hedge which God has set, and follow the conduct of the world and the flesh; and they go astray like lost sheep. 2. The sinner at his rest, or rather his ruin: He shall remain ( quiescet — he shall rest, but not in pace — in peace ) in the congregation of the giants, the sinners of the old world, that were swept away by the deluge; to that destruction the damnation of sinners is compared, as sometimes to the destruction of Sodom, when they are said to have their portion in fire and brimstone. Or in the congregation of the damned, that are under the power of the second death. There is a vast congregation of damned sinners, bound in bundles for the fire, and in that those shall remain, remain for ever, who are shut out from the congregation of the righteous. He that forsakes the way to heaven, if he return not to it, will certainly sink into the depths of hell.

17 He that loveth pleasure shall be a poor man: he that loveth wine and oil shall not be rich.
Here is an argument against a voluptuous luxurious life, taken from the ruin it brings upon men's temporal interests. Here is 1. The description of an epicure: He loves pleasure. God allows us to use the delights of sense soberly and temperately, wine to make glad the heart and put vigour into the spirits, and oil to make the face to shine and beautify the countenance; but he that loves these, that sets his heart upon them, covets them earnestly, is solicitous to have all the delights of sense wound up to the height of pleasurableness, is impatient of every thing that crosses him in his pleasures, relishes these as the best pleasures, and has his mouth by them put out of taste for spiritual delights, he is an epicure, 2 Tim. iii. 4 . 2. The punishment of an epicure in this world: He shall be a poor man; for the lusts of sensuality are not maintained but at great expense, and there are instances of those who want necessaries, and live upon alms, who once could not live without dainties and varieties. Many a beau becomes a beggar.

18 The wicked shall be a ransom for the righteous, and the transgressor for the upright.
This intimates, 1. What should be done by the justice of men: The wicked, that are the troublers of a land, ought to be punished, for the preventing and turning away of those national judgments which otherwise will be inflicted and in which even the righteous are many times involved. Thus when Achan was stoned he was a ransom for the camp of righteous Israel; and the seven sons of Saul, when they were hanged, were a ransom for the kingdom of righteous David. 2. What is often done by the providence of God: The righteous is delivered out of trouble, and the wicked comes in his stead, and so seems as if he were a ransom for him, ch. xi. 8 . God will rather leave many wicked people to be cut off than abandon his own people. I will give men for thee, Isa. xliii. 3, 4 .
