Charles H. Spurgeon on Psalms 35:8

"Let destruction come, upon him at unawares." This tremendous imprecation is frequently fulfilled. God's judgments are often sudden and signal. Death enter the persecutor's house without pausing to knock at the door. The thunderbolt of judgment leaps from its hiding-place, and in one crash the wicked are broken for ever. "And let his net that he hath hid catch himself: into that very destruction let him fall." There is a lex talionis with God which often works most wonderfully. Men set traps and catch their own fingers. They throw up stones, and they fall upon their own heads. How often Satan outwits himself, and burns his fingers with his own coals! This will doubtless be one of the aggravations of hell, that men will torment themselves with what were once the fond devices of their rebellious minds. They curse and are cursed; they kick the pricks and tear themselves; they pour forth floods of fire, and it burns them within and without.
