Charles H. Spurgeon on Psalms 21:9

"As a fiery oven." Shall make them like a vault of fire, literally, "an oven," as in our translation, or "furnace of fire." Bishop Horsley remarks, "It describes the smoke of the Messiah's enemies perishing by fire, ascending like the smoke of a furnace. 'The smoke of their torments shall ascend for ever and ever.'" How awfully grand is that description of the ruins of the cities of the plain, as the prospect struck on Abraham's eye on the fatal morning of their destruction! "And he looked toward Sodom and Gomorrah, and toward all the land of the plain, and beheld, and, lo, the smoke of the country went up as the smoke of a furnace." Milton puts it —

"Overhead the dismal hiss

Of fiery darts in flaming volleys flew,

And flying vaulted either host with fire." Richard Mant.
