For the terrible one - The violent one (עריץ ‛ârı̂yts), the oppressor, who had exercised cruelty over them. This, I suppose, refers to the haughty among the Jews themselves; to those who held offices of power, and who abused them to oppress the poor and needy.
And the scorner - (see Isaiah 28:14, Isaiah 28:22).
Is consumed - Shall be entirely destroyed.
And all that watch for iniquity - That is, who anxiously seek for opportunities to commit iniquity.
