That say ... - They add one sin to another for “the purpose of defying” God, and provoking him to anger. They pretend that he will not punish sin; and hence, they plunge deeply into it, and defy him to punish them.
Let him make speed - Let him come quick to punish.
And hasten his work - His punishment.
That we may see it - An expression of defiance. We would like to see him undertake it.
The counsel of the Holy One ... - His threatened purpose to punish. This is the language of all sinners. They plunge deep into sin; they mock at the threatenings of God; they defy him to do his utmost; they do not believe his declarations. It is difficult to conceive more dreadful and high-handed iniquity than this.
