John Gill's Exposition of the Whole Bible
Proverbs 12:25
Heaviness in the heart of man maketh it stoop,.... Either an anxious care and solicitude about living in the world, as the word m signifies; when it seizes a man's spirits, it depresses them, and keeps them down: or a fear and dread of adversity, or sorrow and grief, on account of some calamity and distress; when it gets into a man's heart, it sinks and bows it down, that it cannot take any pleasure or comfort in anything. The Septuagint and Arabic versions render it, a "terrible word troubles the heart of a just man"; or "troubles the heart of man", as the Syriac version; the Targum is,
"a word of fear in the heart of man causes fear:''
such is the law, which is a word of terror; which speaks terrible things to men; fills the mind with terror; works wrath in the conscience, and induces a spirit of bondage to fear; bows and keeps under the spirits of men, through a fearful looking for of judgment and fiery indignation;
but a good word maketh it glad; a comforting, cheering, and encouraging word from any friend, that compassionates their distressed case; this lifts up the heart and inspires it with joy; so a word in season, spoken by a Gospel minister, raises up a soul that is bowed down, and gives it comfort and joy: such a good word is the Gospel itself; it is good news from a far country, which is like cold water to a thirsty soul, very refreshing and reviving. The Septuagint and Arabic versions here render it, "a good message", and such the Gospel is; which, when brought to the heart of a poor sinner, depressed with the terrors of the law, causes joy in it; such is the word of peace, pardon, righteousness, and eternal life by Christ; such is the word that he himself spoke, Matthew 9:2. Kimchi instances in Psalms 55:22.
