The destroyer (Isa 33:1-33:1)

“Woe to you!

Destroyer!

You yourself have not been destroyed!

You treacherous one!

With whom no one has dealt treacherously!

When you have ceased to destroy,

You will be destroyed.

When you have stopped dealing treacherously,

You will be dealt with treacherously.”

This section seems to be a later addition of prayers led by a prophet in the various religious services. The prophetic term destroyer here refers to Babylon. Although it has not yet been destroyed, it will be. No has dealt treacherously with them, but they have dealt treacherously with others. The destroying days of Babylon are numbered. They will be dealt with treacherously.
