The chapter begins with a woe on those who decree unrighteous decrees and write oppressive sentences to deprive the poor, widows and orphans. The Lord asks what they will do on the day of punishment and of ruin that comes from afar.
Then the Lord pronounces woe on Assyria, the rod of his anger and the staff of his fury, sent against a godless nation. But Assyria does not see it that way: in its heart is to destroy and cut off nations, and it boasts of its victories over cities and kings. When the Lord has finished his work on Mount Zion and in Jerusalem, he will punish the fruit of the arrogance of the king of Assyria. He asks whether the axe boasts over the one who chops with it, or the saw magnifies itself against the one who wields it. So the Lord will send wasting sickness among its warriors and kindle a fire, and the glory of its forest will be consumed; the trees left will be so few that a child could count them.
On that day the remnant of Israel and the survivors of Jacob will no longer lean on the one who struck them but will lean on the Lord, the Holy One of Israel. A remnant will return to the mighty God. Though Israel be like the sand of the sea, only a remnant will return, and the destruction decreed will bring righteousness. So the Lord tells his people who dwell in Zion not to fear Assyria, for in a very little while the anger will end. The chapter then describes the Assyrian army's march through towns north of Jerusalem and ends with the Lord, who by his power will fell the tall trees of Lebanon.
