9:8–10:4 This is a very carefully constructed section in which judgment is pronounced on the nation. Four reasons are given, each followed by a grim formula declaring that there is more judgment to come (9:12, 17, 21; 10:4)

Here the message is particularly addressed to Israel, whose downfall is near, but it also serves as a warning to Judah. The word “fall” (Hb. napal; 9:8) also occurs in 10:4, forming an inclusio and showing the unity of the section.

9:9–12 The first sin, underlying all the others, is an overwhelming pride that refuses to accept limitations. If the invaders remove mudbricks and sycamore trees, the Israelites claim they will simply replace them with fine stone and impressive cedars. In fact, Yahweh is judging them by sending Syrians and Philistines against them. These enemies come not of their own volition but because Yahweh sends them (cf. 10:5). The sad reality, evident from 2 Kings 15, is that the northern kingdom is lurching from one short-lived reign to another, churning through six kings in twenty years. Judgment has begun, but there is more to come.

9:13–17 The people are corrupt from top to bottom, but this second sin relates especially to poor leadership. Having failed to take Yahweh seriously, the people kowtow to inadequate leaders who turn them ever further from the true way. “Head and tail” and “branch and reed” are merisms indicating totality.

The prophet explains his metaphor: the prophets who should have been leading in the way of truth have become the religious tail wagging the political dog. This has resulted in a self-perpetuating elite whose only concern is maintaining power. Society has become completely godless, and both military prowess and protection of the vulnerable have fallen by the wayside. Instead of obeying Yahweh’s word, society is awash with godless action and foolish thought. Thus for a second time the ominous judgment formula sounds.

9:18–21 This third stanza addresses the breakdown of natural affections and the destruction of community spirit. Wickedness is self-destructive but is also caught up in the overwhelming fire of God’s holiness. The gluttony and greed of the people is suggested in their craving of food on both sides but still failing to satisfy their hunger. The northern tribes hate and attack each other and are united only in their enmity for Judah. For the third time the judgment oracle is spoken.

10:1–4 The final stanza of the poem again returns to wretched leadership; they not simply are feckless and incompetent but propagate deliberate institutional injustice to preserve the power of the ruling class and to oppress the weak. Laws are heavily weighted against the poor and vulnerable. But the rulers will be hoist with their own petard as they themselves become the helpless ones on the “day of punishment.” Their wealth will vanish as they become cowering prisoners. For a fourth time the bell tolls, and judgment comes nearer.

10:5–6 Assyria is an instrument, a rod and staff in Yahweh’s hand (but to punish, not to protect; cf. Ps. 23:4). The sense here is paralleled in Habakkuk 1:6 in reference to Babylon. The Assyrian invasion is no accident of history; like all nations they are under the hand of Yahweh. The result will be the devastation of Israel and the near destruction of Judah. This is the world as seen by the one who sits in the heavens while the nations plot and bluster (Psalm 2)

10:7–9 The Assyrian king sees things differently. He thinks he sits on the throne of the universe, holding the destinies of nations in his hand. He has no sense that Yahweh controls him. The states he has already captured show that his commanders have more status than those states’ “kings.” The cities conquered are mentioned in geographical terms, from Carchemish on the Euphrates in the north to Calno and Hamath some 50 miles (80 km) to the southwest, with Arpad in a similar region. Further south is Damascus, and still further south is Samaria.

10:10–11 To destroy a nation is to defeat its gods; Samaria and Jerusalem are amateur idolaters and so have no hope in the eyes of the Assyrian king. This is true in the case of Samaria but will not be in the case of Zion. To the Assyrians, gods are simply part of the universe; they have not yet encountered Yahweh, Maker of heaven and earth.

10:12 From the Assyrian worldview we turn to Yahweh’s, with a powerful reminder that the Assyrian invasion is his work. The final part of this section contrasts the view of events seen from earth with that from heaven. Yahweh indeed is judging his people, but the use of the covenant name here reminds us that judgment is not the final word, while “finished” is a reminder that he never leaves work uncompleted. The Assyrian king is an open book to Yahweh: he sees both his inner arrogance and his outward scorn.

Some have argued that verse 12 (which is in prose) is an interpolation. However, the verse makes perfect sense in context as Yahweh speaks of himself in the third person. This is a statement of the reality of the situation, as opposed to the vantage point of Assyrian boasting. Yahweh is Lord of history; his verdict is the one that matters.

10:13–14 How grandiose are the Assyrian’s claims! Their king thinks he has not only unlimited power but boundless wisdom. He rules the nations, obliterating their boundaries, removing their wealth, and deposing their kings. To him the nations are no more than a bird’s nest from which he steals eggs. He bestrides the world like a god; no one can stand up to him.

10:15 How different is the reality! Far from being a god, the Assyrian monarch is something less than human, a mere instrument in the hand of the true God. All the activity is on Yahweh’s part, while the Assyrian boasting is not only arrogant but stupid. The king of Assyria may be active, filling the earth with terror, but he is only a “rod” used by God in his purposes of judgment.

10:16–17 Judgment is now pronounced on Assyria under two metaphors: wasting sickness, which suggests gradual decay, and blazing fire, suggesting total destruction. The military power (“stout warriors”) and imperial splendor (“glory”) will vanish. Although Judah will be judged, she is still Yahweh’s light to the nations, from whom the true illumination will come. Assyria will be destroyed by the blazing holiness Isaiah saw in the heavenly temple (6:3); one day the whole earth will be filled with the glory of God.

10:18–19 Forest and fruitful land together express the complete devastation of Assyria. Again, the metaphor of wasting sickness suggests inevitable decay. The proud will be so diminished that even a child will no longer be afraid of them.

10:20 “In that day,” while referring to the immediate situation outlined in chapter 7 of the removal of both the Syro-Ephraimite threat and the greater one from Assyria, also points to the coming of God’s kingdom and the final defeat of all his enemies. Ahaz has foolishly relied on Assyria coming to help; instead, as Hezekiah will do (37:14–20), he and his followers should lean on Yahweh, their Holy God and Savior.

10:21–23 The message of Shear-jashub (7:3) is reinforced: a remnant will return. This necessitates true repentance and coming to the mighty God, God the warrior, the God of the exodus, the Immanuel whose kingdom will come. The phrase “sand of the sea” recalls the promise to Abraham (Gen. 22:17) and perhaps is best understood in the light of “in that day.” Only a remnant will return after the exile (Ezra 2), but at the end God’s people will indeed be a “great multitude that no one could number” (Rev. 7:9). The first remnant may seem small, but they are truly God’s people: Ezra 3 emphasizes the fact that they will reinstate the great festivals of “Moses the man of God” (Ezra 3:2) and are heirs to the earlier promises (Ezra 3:11). The remnant will ultimately see the coming of Immanuel. Destruction of evil is necessary for the establishment of righteousness. The culmination of the activity of the Lord God of hosts will be his reasserting his lordship over the earth.

10:24–27 The threat of Assyria to Zion is described in language evoking the exodus. Faith in both Testaments is based on who God is and what he has done (1 Cor. 15:3–8). The story of the defeat of Midian is again referenced (cf. Isa. 9:4). The God who rescued his people from Egypt will rescue Jerusalem when the angel of Yahweh destroys Sennacherib’s army (37:36). The “yoke” and the “burden” are again exodus language. The former oppression was removed; so too will be the Assyrian oppression. The last clause of 10:27 (“The yoke will be broken because of the fat”) is difficult. Perhaps it refers back to verse 16, in which Assyria’s “stout warriors” (lit., “fat ones”) are destroyed. Motyer’s suggestion is helpful and probably as near to the meaning as we can get: “Their inner resources are not equal to the challenge, but Israel has a secret fatness of which they know nothing.”30

10:28–32 Assyria is still a formidable threat, and a vivid poetic passage speaks of the terrifying advance of their armies. Sennacherib approached Jerusalem from Lachish in the southwest (36:2), whereas this passage clearly describes a relentless progress from the north in terms of key places on the road to Jerusalem. This may be simply a poetic evocation of the march of a northern enemy. In the same way Jeremiah, speaking of the Babylonians, refers to the north from which disaster will come, although Nebuchadnezzar’s final assault follows much the same route as Sennacherib’s (Jer. 1:13–15). It is also entirely possible that when Samaria falls, the Assyrians send a chariot division south to shake the mailed fist at Jerusalem. Either way, the terrifying power of Assyria is emphasized.

The Assyrians are already near Jerusalem. Aiath, probably Ai (Josh. 7:2), is only 15 miles (24 km) to the north, with Migron being the region around it; Michmash is a key pass into Judah’s territory and a place where the invader might stop. But the Assyrians press on to Geba at the other side of the pass, and the towns on the direct road to the holy city are personified as wailing, panicking, and fleeing. Anathoth, Jeremiah’s hometown (Jer. 1:1), is only 5 miles (8 km) to the northwest. Nob is probably Mount Scopus, just 1 mile (1.6 km) from the city. Isaiah 10:32 lends support to the idea that Isaiah is speaking of a raiding party after Samaria has fallen. In any case Judah will experience the Assyrians approaching not simply to shake the fist but to devastate and destroy Jerusalem (chs. 36–37).

10:33–34 Yet the all-conquering Assyrians will be met by a greater warrior with far more powerful hosts at his disposal. These verses not only put the Assyrian threat in perspective but form a natural transition to the poem about the royal Messiah in chapters 11–12. The powerful forest of trees that is the Assyrian Empire will be cut down, while the seed of David will grow and fill the earth. The Assyrians boast in power akin to the majestic cedars of Lebanon, but their fall will be like that of mighty cedars. The actual story of their fall is told in chapters 36–37, but here the emphasis is on the greatness of Yahweh and the weakness of humanity, in the context both of present troubled times and of those around Immanuel’s coming.
