Proverbs 18:14 - Joseph Benson’s Commentary on the Old and New Testaments

The spirit of a man That is, his soul, namely, not wounded, as appears by the opposite branch of the verse, and which is vigorous and cheerful, supported by a sense of God's love, the consciousness of its own integrity, and of its present peace with him, and by a bright prospect of future happiness; will sustain his infirmity Will easily support him under any bodily or outward troubles, as God's people have often found by experience; but a wounded spirit Depressed and dejected with a sense of its own guilt, depravity, and misery; who can bear? It is most grievous and intolerable, if divine support and comfort be withheld.
