Proverbs 18:14 - Matthew Poole's English Annotations on the Holy Bible

The spirit, i.e. the soul, to wit, which is unwounded, as appears by the opposite branch of the verse; which is vigorous and cheerful, supported by the sense of God's love, and the conscience of its own integrity, and the prospect of its present peace and future happiness. Will sustain his infirmity; will easily support him under any bodily or outward troubles, as God's people have oft found by experience. Wounded; dejected with the sense of its own guilt and misery. Who can bear? it is most grievous and intolerable without Divine assistance.
