Fury is not in me: who would set the briers and thorns against me in battle? I would go through them, I would burn them together.
Fury is not in me - i:e., I entertain no longer anger toward my vine.
Who would set the briers and thorns against me in battle? - i:e., would that I had the briers, etc. (the wicked foe: Isaiah 9:18; Isaiah 10:17; 2 Samuel 23:6), before me!
I would go through - literally, 'I would go forward (as an enemy) in them.' My contest is no longer with my vineyard, but with the thorns that have molested it.
