My people went down... — Stress is laid on the unprovoked character of the oppression in the case both of Egypt and the Assyrian invaders Sargon and Sennacherib. It is possible that Assyria may be used in its wider sense as including Babylon. If so, the fact tends to the conclusion that the book was written at a time when the kings of Assyria included Babylon in their titles. Probably, however, the prophet refers to the deliverance from the army of Sennacherib as a pledge of the deliverance from Babylon.
