Isaiah 33:1

Woe to thee that spoilest, and thou wast not spoiled, the hostility of the Assyrian invader being a type of the world-power's enmity toward the Church of God; and dealest treacherously, in invading the country for the purpose of robbery, and they dealt not treacherously with thee, the hostile act being altogether unprovoked. When thou shalt cease to spoil, when the measure of damage which the plans of God included had been reached, thou shalt be spoiled; and when thou shalt make an end to deal treacherously, they shall deal treacherously with thee. The text clearly indicates that the punishment of him who had been unpunished would certainly come upon him. The prophet's threat now turns into a pleading petition to the Lord.
