Therefore he hath poured upon him the fury of his anger - His righteous indignation in the overturning of their nation, the destruction of their temple and city, and in carrying them captive into a distant land.
And it hath set him on fire - That is, the fury of Yahweh kindled the flame of war all around the Jewish nation, and spread desolation everywhere.
Yet he knew not - They refused to attend to it, and lay it to heart. They pursued their ways of wickedness, regardless of the threatening judgments, and the impending wrath of God. They did not consider that these evils were inflicted for their crimes, nor did they turn from their sins when they were thus threatened with the wrath of God.
