| Gill's Exposition of the Entire Bible He that hath no rule over his own spirit,.... His affections and passions, puts no restraint, unto them, as the word signifies; no guard against them, no fence about them, to curb his curiosity, to check his pride and vanity, to restrain his wrath and anger and revenge, and keep within due bounds his ambition and itch of vainglory; is like a city that broken down and without walls; into which the may go with pleasure, and which is exposed to the rapine and violence of everyone; and so a man that has no command of himself and passions, but gives the reins to them, is exposed to the enemy of souls, Satan and is liable to every sin, snare and temptation.
Keil and Delitzsch Biblical Commentary on the Old TestamentThis verse, counselling restraint as to the spirit, is connected with the foregoing, which counsels to self-control as to enjoyment: A city broken through, now without walls - A man without self-control over his spirit. A "city broken down" is one whose wall is "broken," 2 Chronicles 32:5, whether it has met with breaches (פּרצים), or is wholly broken; in the former case also the city is incapable of being defended, and it is all one as if it had no wall. Such a city is like a man "who hath no control over his own spirit" (for the accentuation of the Heb. words here, vid., Thorath Emeth, p. 10): cujus spiritui nulla cohibitio (Schultens), i.e., qui animum suum cohibere non potest (Fleischer: עצר, R. צר, to press together, to oppress, and thereby to hold back). As such a city can be plundered and laid waste without trouble, so a man who knows not to hold in check his desires and affections is in constant danger of blindly following the impulse of his unbridled sensuality, and of being hurried forward to outbreaks of passion, and thus of bringing unhappiness upon himself. There are sensual passions (e.g., drunkenness), intellectual (e.g., ambition), mingled (e.g., revenge); but in all of these a false ego rules, which, instead of being held down by the true and better ego, rises to unbounded supremacy. (Note: Vid., Drbal's Empirische Psychologie, 137.) Therefore the expression used is not לנפשׁו, but לרוּחו; desire has its seat in the soul, but in the spirit it grows into passion, which in the root of all its diversities is selfishness (Psychol. p. 199); self-control is accordingly the ruling of the spirit, i.e., the restraining (keeping down) of the false enslaved ego-life by the true and free, and powerful in God Himself.

Jamieson-Fausset-Brown Bible Commentary28. Such are exposed to the incursions of evil thoughts and successful temptations.
Matthew Henry's Concise Commentary25:19. Confidence in an unfaithful man is painful and vexatious; when we put any stress on him, he not only fails, but makes us feel for it. 20. We take a wrong course if we think to relieve those in sorrow by endeavouring to make them merry. 21,22. The precept to love even our enemies is an Old Testament commandment. Our Saviour has shown his own great example in loving us when we were enemies. 23. Slanders would not be so readily spoken, if they were not readily heard. Sin, if it receives any check, becomes cowardly. 24. It is better to be alone, than to be joined to one who is a hinderance to the comfort of life. 25. Heaven is a country afar off; how refreshing is good news from thence, in the everlasting gospel, which signifies glad tidings, and in the witness of the Spirit with our spirits that we are God's children! 26. When the righteous are led into sin, it is as hurtful as if the public fountains were poisoned. 27. We must be, through grace, dead to the pleasures of sense, and also to the praises of men. 28. The man who has no command over his anger, is easily robbed of peace. Let us give up ourselves to the Lord, and pray him to put his Spirit within us, and cause us to walk in his statutes.
Matthew Henry's Whole Bible CommentaryVerse 28 Here is, 1. The good character of a wise and virtuous man implied. He is one that has rule over his own spirit; he maintains the government of himself, and of his own appetites and passions, and does not suffer them to rebel against reason and conscience. He has the rule of his own thoughts, his desires, his inclinations, his resentments, and keeps them all in good order. 2. The bad case of a vicious man, who has not this rule over his own spirit, who, when temptations to excess in eating or drinking are before him, has no government of himself, when he is provoked breaks out into exorbitant passions, such a one is like a city that is broken down and without walls. All that is good goes out, and forsakes him; all that is evil breaks in upon him. He lies exposed to all the temptations of Satan and becomes an easy prey to that enemy; he is also liable to many troubles and vexations; it is likewise as much a reproach to him as it is to a city to have its walls ruined, Neh. 1. 3. |
