Charles H. Spurgeon on Psalms 58:9

Before your pots feel the bramble. By this proverbial expression the psalmist describes the sudden eruption of the divine wrath; sudden and violent as the ascension of the dry bramble underneath the housewife's pot. The brightness of the flame which this material furnishes, the height to which it mounts in an instant, the fury with which it seems to rage on all sides of the vessel, give force, and even sublimity to the image, though taken from one of the commonest occurrences of the lower life —a cottager's wife boiling her pot! The sense, then, will be: "Before your pots feel the bramble, he shall sweep them away in whirlwind and hurricane." Samuel Horsley, 1733-1806.
