| Barnes' Notes on the Bible The three forms of evil that destroy reputation and tempt to waste are brought together. Drowsiness - Specially the drunken sleep, heavy and confused.
Gill's Exposition of the Entire BibleFor the drunkard and the glutton shall come to poverty,.... They consuming their substance upon their bellies, in eating and drinking; see Proverbs 21:17; and drowsiness shall clothe a man with rags; excessive eating and drinking brings drowsiness on men, unfits them for business, and makes them idle and slothful; and spending all on their bellies, they have nothing for their backs, and are clothed in rags; see Proverbs 24:33.
Geneva Study BibleFor the drunkard and the glutton shall come to poverty: and drowsiness shall clothe a man with rags.
Jamieson-Fausset-Brown Bible Commentary21. drowsiness-the dreamy sleep of the slothful.
Matthew Henry's Concise Commentary23:19-28 The gracious Saviour who purchased pardon and peace for his people, with all the affection of a tender parent, counsels us to hear and be wise, and is ready to guide our hearts in his way. Here we have an earnest call to young people, to attend to the advice of their godly parents. If the heart be guided, the steps will be guided. Buy the truth, and sell it not; be willing to part with any thing for it. Do not part with it for pleasures, honours, riches, or any thing in this world. The heart is what the great God requires. We must not think to divide the heart between God and the world; he will have all or none. Look to the rule of God's word, the conduct of his providence, and the good examples of his people. Particular cautions are given against sins most destructive to wisdom and grace in the soul. It is really a shame to make a god of the belly. Drunkenness stupifies men, and then all goes to ruin. Licentiousness takes away the heart that should be given to God. Take heed of any approaches toward this sin, it is very hard to retreat from it. It bewitches men to their ruin. |
