“For the violence done to Lebanon will overwhelm you, as will the destruction of the animals that terrified them.” This seems to be a reference to the fact that when the Babylonians came through Lebanon, they cut down many of the trees and destroyed the environment the animals lived in. They would have used the wood for military purposes, from everything from carts and chariots to wood for siege works, but it is also possible that some of the wonderful wood of Lebanon was sent back to Babylon to be used in building palaces, temples, etc. They would have also hunted and ate the animals that lived there. Now the violence that they did to woods and animals will come upon them. There are places in the Bible where the leaders of Judah are compared to the cedars of Lebanon, and because of that some commentators think the whole verse refers to destruction in the Promised Land, but there is no need to apply a figurative meaning here. The literal makes perfect sense, that both Lebanon and other lands, along with Judah, are included.
