Imagine an enemy sweeping through your land, taking everything, yet claiming they were attacked first. This is the picture painted here.
Isaiah starts with a powerful declaration, a 'woe,' directed at an aggressor. The core of this denunciation is the unprovoked nature of their violence.
Ruthless Plunder
The attacker is described as one 'that spoilest, and thou wast not spoiled.' This means they are actively destroying and taking, but they themselves have not suffered similar destruction at the hands of those they are attacking. Their actions are pure aggression, not a response to injury.
Deceptive Tactics
This is compounded by the charge of treachery: 'and dealest treacherously, and they dealt not treacherously with thee!' The aggressor uses deceit and betrayal, yet has not been betrayed in return by their victim. This highlights their unjust and morally bankrupt approach to conflict.
