Here again the Prophet shows that the vengeance of God would be just against Israel, because they willingly followed the impious edicts of their king. The people might indeed have appeared to be excusable, since religion had not been changed by their voice, or by public consent, or by any contrivance of the many, but by the tyrannical will of the king alone: Jeroboam was not induced by superstition, but by subtile wickedness, to erect altars elsewhere, and not at Jerusalem. The people then might have appeared to be without blame; for the king alone devised this artifices to secure himself from danger. But the Prophet shows that all were implicated in the same guilt before God, because the people adopted with alacrity the impious forms of worship which the king had commanded. He therefore says, that Ephraim is exposed to plunder, that he is broken by judgment, (or, "shall be broken," for the words may be rendered in the future tense.) That the people then were thus torn, and were also to bear in future far more grievous things, was not, as he says, because they had to suffer all these things undeservedly, for they were not innocent. -- How so? Because they willingly followed the commands of their king; for the king did not force them to forsake the doctrine of the law, but every one went voluntarily after impious superstitions. Since then they willingly obeyed their king, they could not now excuse themselves, they could not object that this was done by one man, and that they were not admitted to consult with him. Their promptitude proved them to be perfidious. Some render hv'yl, evail, to begin," and y'l, ial, is often taken in this sense: but as it oftener signifies, "to be willing," the Prophet no doubt means here, that the Israelites had not been compelled by force and fear to go astray after superstitions; but that they were prompt and ready to obey, for there was in them no fear of God, no religion. If any one should now ask, whether they are excusable, who are tyrannically drawn away into superstitions, as we see to be done under the Papacy, the answer is ready, that those are not here absolved who regarded men more than God: nor is terror, as we know, a sufficient excuse, when we prefer our own life to the glory of God, and when, anxious to provide for ourselves and to avoid the cross, we deny God, or turn aside from making a confession of the right and pure faith: but the fault is rendered double, when men easily comply with any thing commanded by tyrants; for they show, that they were already fully inclined to despise God and to deny true religion. Hence the impiety of Jeroboam discovered the common ungodliness and wickedness of the whole people; for as soon as he raised his finger and bid them to worship God corruptly, all joyfully followed the impious edict. There was an occasion then offered to them; but the evil dwelt before in their hearts; for they were not so inclined and prompt to obey God. We now then see what the Prophet had in view. He says that God would justly punish all the Israelites, yea, even all the common people; for though Jeroboam alone had commanded them to worship God corruptly, yet all of them willingly embraced what he wished to be done: and thus it became manifest that they had in them no fear of God. We now see how vain is the excuse of those who say that they ought to obey kings, and at the same time forsake the word of God: for what does the Prophet reprove here, but that the Israelites had been too submissive to their king? "But this in itself was worthy of praise." True, when the king commanded nothing contrary to God's word; but when he perverted God's worship, when he set up corrupt superstitions, then the people ought to have firmly resisted him: but as they were too pliant, nay, willingly allowed themselves to be drawn away from the true worship of God, the Prophet says here, that they had no reason to complain, that they were too sharply and too severely chastised by the Lord. It follows --

Ephraim is oppressed and broken in judgment - Literally, "crushed in judgment." Holy Scripture, elsewhere also, "combines" these same two words, rendered "oppressed" and "crushed," in speaking of man's oppression by man. Ephraim preferred man's commands and laws to God's; they obeyed man and set God at nought; therefore they should suffer at man's hands, who, while he equally neglected God's will, enforced his own. The "commandment," which "Ephraim willingly went after," was doubtless that of Jeroboam; "It is too much for you to go up to Jerusalem; behold thy gods, O Israel, which brought you out of the land of Egypt; and Jeroboam ordained a feast unto the children of Israel" 1-Kings 12:28, 1-Kings 12:32-33. Through this "commandment," Jeroboam earned the dreadful title, "who made Israel to sin." And Israel "went willingly after it," for it is said; "This thing became a sin; and the people went to worship before the one, even unto Daniel:" i. e., while they readily accepted Jeroboam's plea. It "is too much for you to go up to Jerusalem," they "went willingly" to the Northernmost point of Palestine, "even to Daniel." For this sin, God judged them justly, even through the unjust judgment of man. God mostly punishes, through their own choice, those who choose against His. The Jews said, "we have no king but Caesar," and Caesar destroyed them.

Walked after the commandment - Jeroboam's commandment to worship his calves at Daniel and Beth-el. Many of them were not forced to do this, they did it willingly.

Ephraim [is] oppressed [and] broken in judgment, because he willingly walked after the (l) commandment.
(l) That is, after King Jeroboam's commandment, and did not rather follow God.

Ephraim is oppressed, and broken in judgment,.... Here the prophet again returns to the ten tribes, who were oppressed and broken, either by their own judgments, as the Targum; by the tyranny of their kings, and the injustice of their judges, who looked only for the mammon of unrighteousness; or by the judgment of their enemies, the Assyrians, the taxes they laid upon them, the devastations they made among them, and by whom, at last, they were carried captive; or by the judgments of God upon them; for all the enemy did was by his permission, and according to his will:
because he willingly walked after the commandment; not after the commandment of God, but after the commandment of men, as Aben Ezra; or after the commandment of the prophets of Baal, as Jarchi; or after the commandment of Jeroboam the son of Nebat, as Kimchi, by worshipping the calves at Daniel and Bethel he set up there.

broken in judgment--namely, the "judgment" of God on him (Hosea 5:1).
walked after the commandment--Jeroboam's, to worship the calves (2-Kings 10:28-33). Compare Micah 6:16, "the statutes of Omri," namely, idolatrous statutes. We ought to obey God rather than men (Acts 5:29). JEROME reads "filthiness." The Septuagint gives the sense, not the literal translation: "after vanities."

From these judgments Israel and Judah will not be set free, until in their distress they seek their God. This thought is expanded in the next strophe (Hosea 5:11-15). Hosea 5:11. "Ephraim is oppressed, broken in pieces by the judgment; for it has wished, has gone according to statute." By the participles ‛âshūq and râtsūts, the calamity is represented as a lasting condition, which the prophet saw in the spirit as having already begun. The two words are connected together even in Deuteronomy 28:33, to indicate the complete subjection of Israel to the power and oppression of its foes, as a punishment for falling away from the Lord. Retsuts mishpât does not mean "of broken right," or "injured in its right" (Ewald and Hitzig), but "broken in pieces by the judgment" (of God), with a genitivum efficientis, like mukkēh Elōhı̄m in Isaiah 53:4. For it liked to walk according to statute. For הלך אחרי compare Jeremiah 2:5 and 2-Kings 18:15. Tsav is a human statute; it stands both here and in Isaiah 28:10, Isaiah 28:13, the only other passages in which it occurs, as an antithesis to the word or commandment of God. The statute intended is the one which the kingdom of Israel upheld from beginning to end, viz., the worship of the calves, that root of all the sins, which brought about the dissolution and ruin of the kingdom.

Ephraim - The ten tribes are by seditions, civil wars, unjust sentences, and bloody conspiracies eaten up already. After the commandment - To forbear going to the temple, and to worship the calves at Daniel and Bethel, as Jeroboam the son of Nebat commanded.
