Isaiah 32:19

The forest is a figure of soldiers (Isaiah 10:18; Isaiah 10:33-34) and of the fallen world (Isaiah 2:12-13). The city refers to Jerusalem, but it also represents humankind organized in rebellion against God (Isaiah 24:10). Thus both the near and the far views of God’s actions blend here. God will destroy, the hail representing His devastating intervention in human life, both the Assyrian soldiers soon and the fallen world later (cf. Isaiah 10:34). He would devastate Jerusalem soon and rebellious humankind later.
