Charles H. Spurgeon on Psalms 5:9

"Their throat is an open sepulchre." This doth admonish us, (1) that the speeches of natural unregenerate men are unsavory, rotten, and hurtful to others; for, as a sepulchre doth send out noisome savours and filthy smells, so evil men do utter rotten and filthy words. (2) As a sepulchre doth consume and devour bodies cast into it, so wicked men do with their cruel words destroy others; they are like a gulf to destroy others. (3) As a sepulchre, having devoured many corpses, is still ready to consume more, being never satisfied, so wicked men, having overthrown many with their words, do proceed in their outrage, seeking whom they may devour. Thomas Wilson, 1653.
