2 Kings 19:18

Have cast their gods into the fire - In general the Assyrians carried off the images of the gods from the temples of the conquered nations, and deposited them in their own shrines, as at once trophies of victory and proof of the superiority of the Assyrian deities over those of their enemies. But sometimes the gods are said to have been “destroyed” or “burnt with fire;” which was probably done when the idols were of rude workmanship or coarse material; and when it was inconvenient to encumber an army with spoils so weighty and difficult, of transport.
