Charles H. Spurgeon on Psalms 140:11

Evil shall hunt the violent man to overthrow him. 'Tis an allusion to hounds that are of a quick scent, and pursue the game with pleasure; they do not see the deer or the hare, yet they follow upon the scent; and though they have sometimes a very cold and dead scent, yet they will follow and work it out. Thus "evil shall hunt the violent man to overthrow him"; and though sometimes he hath, as it were, got out of the view or sight of evil, and thinks himself under covert, yet these evils, like a company of greedy hounds, will pursue till they have overtaken and overthrown him. —Joseph Caryl.
