As the fire burneth the wood
Or "forest" F13; which is sometimes done purposely, and sometimes through carelessness, as Virgil F14 observes; and which is done very easily and swiftly, when fire is set to it; even all the trees of it, great and small, to which an army is sometimes compared, ( Isaiah 10:18 Isaiah 10:19 ) , and as the flame setteth the mountains on fire; either the mountains themselves, as Etna, Vesuvius, and others; or rather the grass and trees that grow upon them, smitten by lightning from heaven, which may be meant by the flame: in like manner it is wished that the fire and flame of divine wrath would consume the confederate enemies of Israel, above mentioned; as wicked men are but as trees of the forest, and the grass of the mountains, or as thorns and briers, to the wrath of God, which is poured out as fire, and is signified by everlasting burnings.
