Isaiah 9:20
And he shall snatch on the right hand, and be hungry; and he shall eat on the left hand, and they shall not be satisfied: they shall eat every man the flesh of his own arm: And he shall snatch on the right hand, and be hungry; and he shall eat on the left hand, and they shall not be satisfied: they shall eat every man the flesh of his own arm:
Isaiah 9:20 stands within Isaiah's reproof of Judah's sin, belonging to the rebuke delivered in chapters 7-9 against the nation's wrongdoing. That larger chapter was misread by the Jews, who took it to promise a famous and powerful ruler who would lead a successful revolt against Rome. Its message gave no warrant for expecting such a political deliverer.
The sinful conditions exposed in chapters 7-9 typify similar conditions to be found in the last days.
