He that hath no rule over his own spirit is like a city that is {q} broken down, and without walls.

(q) And so is in extreme danger.

Jamieson-Fausset-Brown Bible Commentary

28. Such are exposed to the incursions of evil thoughts and successful temptations.

Matthew Henry's Concise Commentary

25:19. 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 Commentary

Verse 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.
