Charles H. Spurgeon on Psalms 83:14

As the fire burneth a wood. Long years have strewn the ground with deep deposits of leaves; these being dried in the sun are very apt to take fire, and when they do so the burning in terrific. The underwood and the ferns blaze, the bushes crackle, the great trees kindle and to their very tops are wrapped in fire, while the ground is all red as a furnace. In this way, O Lord, mete out destruction to thy foes, and bring all of them to an end. The flame setteth the mountains on fire. Up the hill sides the hanging woods glow like a great sacrifice, and the forests on the mountain's crown smoke towards heaven. Even thus, O Lord, do thou conspicuously and terribly overthrow the enemies of thine Israel.
