Isaiah 10

Verses 5–19 WEB Voices

Alas Assyrian, the rod of the Lord’s anger, the staff in whose hand is His fury. He sends him against a godless nation, to spoil and tread them like mire. But Assyria does not so intend: his heart is to destroy nations. He boasts his commanders are kings; Calno, Hamath, Samaria like the rest; he will do to Jerusalem’s idols as to Samaria’s. When the Lord has finished His work on Zion, He punishes the arrogant heart. The axe must not boast over the hewer. Therefore wasting and fire: the light of Israel becomes a flame; the forest’s remnant so few a child could write their.

Isaiah 10:5

5Alas Assyrian, the rod of my anger, the staff in whose hand is my indignation!

Arminian

Alas Assyrian, the rod of my anger, the staff in whose hand is my fury. Wesley: God’s invitation to take the charge; the instrument wherewith I shall chastise my people; mine anger puts the weapons into their hand.

Assyria is the rod in God’s hand. He is still a rod, not the hand. The fury is the Lord’s.

Reformed

Calvin: God calls the Assyrian as a judge calls an officer. The staff they carry is His anger: everything in their hand is wrath. All their strength proceeds from His wrath. Blind attacks of enemies are regulated by a heavenly providence. Do not suppose anything happens by chance.

Their swords are His anger. Assyria, rod of my anger, staff, fury.

Isaiah 10:6

6I will send him against a profane nation, and against the people who anger me I will give him a command to take the plunder and to take the prey, and to tread them down like the mire of the streets.

Arminian

I will send him against a profane nation, and against the people who anger me I will give him a command to take the plunder and to take the prey, and to tread them down like the mire of the streets. Wesley: send him—by my providence, giving him both occasion and inclination to this expedition.

“Send”—a sending against hypocritical Israel (9:17). Occasion and inclination are still given; the treading is still theirs to do. He sends.

Reformed

Calvin: the rod is not uncertain; appointed for the unthankful. Hypocritical nation: no uprightness. People of His indignation: nothing in them but grounds of anger. I will command him: two ways of commanding—secret decree, and the law that demands voluntary obedience. Fanatics who excuse their wickedness by the decree are guilty of falsehood. The Assyrian has the law; he serves his own lusts. Accidental, as to men, that God acts by the reprobate.

God gives the charge, and Assyria takes the plunder. On this both agree: godless nation, people of my wrath, spoil, mire of the streets.

Isaiah 10:7

7However, he doesn’t mean so, neither does his heart think so; but it is in his heart to destroy, and to cut off not a few nations.

Arminian

However, he doesn’t mean so, neither does his heart think so; but it is in his heart to destroy, and to cut off not a few nations. Wesley: he doth not design the execution of my will, but only to enlarge his own empire. Seasonably added, to justify God in the judgments threatened to the Assyrian. To cut off—to sacrifice multitudes to his own ambition and covetousness.

Assyria has its own purpose: conquest. God uses the empire as his rod, yet the two wills are not the same act, and Assyria is judged for what it meant (v. 12). Arminians find here a clear case of God governing through agents who remain accountable.

Reformed

Calvin: he will not think so. Wicked men vomit rage as if God could not restrain them. Step forth: they are justly chastised by a secret judgment. Nothing farther from the Assyrian than to serve God; yet God works with amazing skill, bringing men to yield obedience without their knowledge or will. Their attempts are totally different; this will not prevent God from executing what He has decreed. The Assyrians will have their turn. God restrains their presumption from carrying into effect whatever they think fit. Lift your eyes to God, whose decree is far beyond that blind fury.

He still does His work by a heart that never meant it. Does not so intend, heart does not so think, destroy, cut off nations.

Key contrast Both confess Assyria is the rod of the Lord’s anger, sent, yet he does not so intend: his heart is empire, not the Lord’s will (10:5–7). Assyria: the decree stands. Arminians hear providence giving occasion and inclination, while Assyria’s own design of empire remains his—and that other intent justifies the later blow (Wesley). Reformed readers hear God impelling the wicked to an object unknown to them: they serve their lusts; He regulates particular acts without dragging the will; they cannot plead the decree against the law (Calvin).

Isaiah 10:8

8For he says, “Aren’t all of my princes kings?

Arminian

Are not my commanders all kings? Wesley: equal for power, wealth, and glory to the kings of other nations.

The word “says” introduces Assyria’s boast. The rod talks like a throne.

Reformed

Calvin: the reason he will not think he is the rod: blinded by pride, he acknowledges no authority superior to his own. Whoever imagines he can do anything, however small, assumes the power of God. Princes so intoxicated they scarcely remember they are men.

The boast is why he cannot see the hand.

Isaiah 10:9

9Isn’t Calno like Carchemish? Isn’t Hamath like Arpad? Isn’t Samaria like Damascus?”

Arminian

Is not Calno like Carchemish? Wesley: have I not conquered one as another, stronger as weaker? Shall not Samaria be as Damascus?

A list of cities. Samaria already in his mouth as done.

Reformed

Calvin: shall it not happen to the unconquered as to the subdued? Wicked men talk of former actions as if they will break through every obstruction without the will of God. He who exalted us will be able to cast us down.

The list is his proof; it is not.

Isaiah 10:10

10As my hand has found the kingdoms of the idols, whose engraved images exceeded those of Jerusalem and of Samaria,

Arminian

As my hand has found the kingdoms of the idols, whose engraved images exceeded those of Jerusalem and of Samaria. Wesley: kingdoms that worshipped their own idols and thought they could protect them. He calls even Jerusalem’s gods idols by contempt, because none delivered their people, and he judged them inferior to the sun, the Assyrian god.

The mention of idols is part of Assyria’s taunt. He ranks Zion with the rest. That ranking is the blasphemy of v. 12.

Reformed

Calvin: he breaks into more outrageous language: not only men but God and the gods he worshipped. First he exalts himself above God; second he makes no distinction between God and false gods. If he despised Apollo, he despised him as having something divine. He placed the living God on a level with heathen gods.

The living God is not in that list.

Isaiah 10:11

11shall I not, as I have done to Samaria and her idols, so do to Jerusalem and her idols?

Arminian

Shall I not, as I have done to Samaria and her idols, so do to Jerusalem and her idols? The next city on the list is Zion.

The words “Shall I” threaten Jerusalem itself. Samaria’s fall does not prove Zion’s God is an idol. The child of 9:6 still sits.

Reformed

Calvin: he ridicules Israel’s confidence as if no greater power belonged to God than to idols. The second blasphemy: the living God leveled with the false.

He will try; v. 12 answers. Jerusalem, her idols, Samaria, her images.

Isaiah 10:12

12Therefore it will happen that when the Lord has performed his whole work on Mount Zion and on Jerusalem, I will punish the fruit of the willful proud heart of the king of Assyria, and the insolence of his arrogant looks.

Arminian

When the Lord has performed his whole work on Mount Zion and on Jerusalem, I will punish the fruit of the willful proud heart of the king of Assyria, and the insolence of his eyes. Wesley: because of this impudent blasphemy. His work—chastising his people so long as he sees fit. Looks—insolent words and carriage.

“When”—Zion first, then the rod. The work on Zion is still His, and the punishment of the boast is still His.

Reformed

Calvin: two clauses—God will punish the king; the time is not yet, that believers may wait. When He shall have chastised the sins of His Church, as a master settling his family, then the rod. Do not despond when the tyrant is exalted. Fruit of the stout heart: pride’s seat. God cannot endure the arrogance of proud men. Whole work: our haste would drag Him off a work only begun. Judgment begins at the house of God, then extends to those without.

“When”—Church first, then the tool. Held in common: finished his work, Zion, Jerusalem, arrogant heart, boastful look.

Isaiah 10:13

13For he has said, “By the strength of my hand I have done it, and by my wisdom, for I have understanding. I have removed the boundaries of the peoples, and have robbed their treasures. Like a valiant man I have brought down their rulers.

Arminian

By the strength of my hand I have done it, and by my wisdom, for I have understanding. I have removed the boundaries of the peoples, and have robbed their treasures. Like a valiant man I have brought down those who sit on thrones. Wesley: invaded their lands and added them; put down—deprived of former glory.

The axe claiming the hewer’s work.

Reformed

Calvin: he ascribes all victories to his power and wisdom. Strength of hand: vast armies. Wisdom: tricks and dishonest cunning by which he gained on his neighbors. Removed boundaries: extended dominion. He claims what belongs to God.

The speech v. 12 will punish. Shared: strength of my hand, wisdom, boundaries, treasures, thrones.

Isaiah 10:14

14My hand has found the riches of the peoples like a nest, and like one gathers eggs that are abandoned, I have gathered all the earth. There was no one who moved their wing, or that opened their mouth, or chirped.”

Arminian

My hand has found the riches of the peoples like a nest; as one gathers eggs that are abandoned, I have gathered all the earth. There was no one who moved their wing, or that opened their mouth, or chirped. Wesley: eggs the dam left; all the riches of the earth—an hyperbole usual in such mouths; peeped—as birds when the nest is robbed.

Assyria speaks of plunder as gathering eggs from a nest. No chirp is his lie; Zion will chirp by the Holy One (v. 17).

Reformed

Calvin: it cost him no trouble. A deserted nest, eggs taken without the parent birds. No one ventured to open the mouth. He attributes this to his wisdom and makes no acknowledgment of providence. These boasts are bellows to kindle judgment.

The earth was not ownerless. Nest, eggs, all the earth, none moved a wing, chirped.

Isaiah 10:15

15Should an ax brag against him who chops with it? Should a saw exalt itself above him who saws with it? As if a rod should lift those who lift it up, or as if a staff should lift up someone who is not wood.

Arminian

Should an ax brag against him who chops with it, or a saw exalt itself above him who wields it? Should a saw exalt itself above him who saws with it? As if a rod should lift those who lift it up, or as if a staff should lift up someone who is not wood. Wesley: how absurd for thee, an instrument, to blaspheme thy Lord, who has as great power over thee as a man over the ax wherewith he heweth.

The rod of v. 5, named. He is still wood. The boast is still sin. Not a fake warning: this question has an answer in v. 16.

Reformed

Calvin: as if an axe despised the hand that moves it. Men rise against God whenever they ascribe to themselves more than is proper. God presides over individual acts, moving men like rods—not a mere general upholding of nature. The question of free-will is unseasonably introduced: if God turns their thoughts, they do not therefore cease to plan. Not violent compulsion; in a wonderful manner He regulates all movements, so they still have the exercise of their will. All efforts are fruitless if God do not grant success.

Particular providence, not a dead staff that still chooses.

Isaiah 10:16

16Therefore the Lord, GOD of Armies, will send among his fat ones leanness; and under his glory a burning will be kindled like the burning of fire.

Arminian

Therefore the Lord, GOD of Armies, will send among his fat ones leanness; and under his glory a burning will be kindled like the burning of fire. Wesley: the sovereign Lord of thine and all armies shall strip him and his princes of wealth, might, glory, and destroy his numerous army as fire does combustibles.

Judgment comes because of the boast. The Lord of hosts outranks this host.

Reformed

Calvin: therefore—because he trusted in wealth and forces. Fatness made lean. Under his glory a burning: the greater the splendor, the more fuel. Nothing left, as a tree cut from the root.

The hewer kindles the axe. Lord God of hosts, wasting, stout warriors, glory, burning, fire.

Isaiah 10:17

17The light of Israel will be for a fire, and his Holy One for a flame; and it will burn and devour his thorns and his briers in one day.

Arminian

The light of Israel will be for a fire, and his Holy One for a flame; and it will burn and devour his thorns and his briers in one day. Wesley: that God who is a comfortable light to his people; a fire to the Assyrians; thorns—his vast army, no more able to resist than dry thorns to fire.

Shared—the Holy One of 6:3 is this flame.

Reformed

Calvin: in fire, light and heat. He consumes enemies by heat and enlightens the godly by light. God is a devouring fire and, in another view, light: contrary effects on godly and ungodly. Holy One: He protects the people He has chosen. In one day: sudden, when they think danger far off. Defenses like tow.

The same Holy One, two effects. Light of Israel, fire, Holy One, flame, thorns, briers, one day.

Isaiah 10:18

18He will consume the glory of his forest and of his fruitful field, both soul and body. It will be as when a standard bearer faints.

Arminian

He will consume the glory of his forest and of his fruitful field, both soul and body. It will be as when a standard bearer faints. Wesley: his great army like a forest for numbers; soldiers thick as ears of corn; soul and body—totally, inwardly and outwardly; like an army when the standard-bearer is slain, panic in the whole.

“Forest”—host thinned. Soul and body: the man and the ranks. Not a chart.

Reformed

Calvin: highest and lowest consumed. From the soul even to the flesh: both unhealthy, most dangerous. Vengeance falls on them also. The flame only scorches the godly; it consumes the ungodly, in whom it finds only fuel. Fainting of a standard-bearer: ensigns taken, great slaughter.

The image of the forest shows that nothing sound will be left. Common ground: glory, forest, fruitful land, soul and body, wastes away.

Isaiah 10:19

19The remnant of the trees of his forest shall be few, so that a child could write their number.

Arminian

The remnant of the trees of his forest shall be few, so that a child could write their number. Wesley: the remainder of that mighty host.

Assyria’s leftover, not Israel’s (that is 10:20). A child can number what was a forest. Few, after the flame of v. 17.

Reformed

Calvin: a Hebrew idiom for few. Once a vast forest; after the trees are hewn, those left are scattered, countable by a child who struggles past three or four.

The rod, numbered. Both traditions agree: remnant, trees of his forest, child could write their number.

Historic quotes

Voices from both camps

What older interpreters in each camp said about a rod that does not mean so, an axe that must not boast, and a Holy One who becomes a flame.

Arminian Notable voices

“O Assyrian—God’s invitation to take the charge and set upon the work. The rod—the instrument of mine anger, wherewith I shall chastise my people. Send him—by my providence, giving him both occasion and inclination to this expedition. Howbeit—he doth not design the execution of my will, but only to enlarge his own empire. Which is seasonably added, to justify God in his judgments threatened to the Assyrian. The ax—how absurd is it, for thee, who art but an instrument in God’s hand, to blaspheme thy Lord and master, who has as great power over thee as a man hath over the ax wherewith he heweth. The light—that God who is and will be a comfortable light to his people. A fire—to the Assyrians. Thorns—his vast army, no more able to resist God than dry thorns are to oppose the fire. Wherefore—because of this impudent blasphemy. His work—of chastising his people so long as he sees fit.”
John Wesley · Explanatory Notes upon the Old Testament (on Isa 10:5–17)

Reformed Notable voices

“O Assyrian: God calls him as an officer to put the malefactor in chains. The staff in their hand is mine indignation: everything in their hand is His wrath. All the strength the enemy possesses proceeds from the wrath of God. Three ways God acts by men: all move and exist by Him; He impels and directs the wicked according as He thinks fit, though nothing is farther from their thoughts; and by His Spirit of sanctification, peculiar to the elect. Two ways of commanding: His secret decree, and His law. Fanatics who excuse wickedness by the decree are guilty of falsehood. The Assyrians had no such intention; they were hurried by lust and ambition. Accidental, so far as relates to men, that He acts by the wicked. He does not so intend: nothing farther from the Assyrian than to serve God; yet God brings men to yield obedience even without their knowledge or will. Shall the axe boast? Men rise up against God whenever they ascribe to themselves more than is proper. He presides over individual acts, and moves men like rods. Not a violent compulsion, as if God dragged them against their will; in a wonderful manner He regulates all the movements of men, so that they still have the exercise of their will. When the Lord hath finished his whole work on Zion: first He chastises the Church; then He visits the pride of the rod. Judgment begins at the house of God.”
