Herod the king was troubled Herod was not unacquainted with the predictions, which promised to the Jews a King, who would restore their distressful and ruinous affairs to a prosperous condition. He had lived from a child among that nation, and was thoroughly acquainted with their affairs. Besides, the report was spread everywhere, and could not be unknown to the neighboring nations. Yet he is troubled, as if the matter had been new and unheard of; because he put no trust in God, and thought it idle to rely on the promises of a Redeemer; and particularly because, with the foolish confidence incident to proud men, he imagined that the kingdom was secure to himself and his descendants. But though, in the intoxication of prosperity, he was formerly accustomed to view the prophecies with scorn, the recollection of them now aroused him to sudden alarm. For he would not have been so strongly moved by the simple tale of the Magi, if he had not remembered the predictions, which he had formerly looked upon as harmless, [1] and of no importance. Thus, when the Lord has permitted unbelievers to sleep, he suddenly breaks their rest. [2] And all Jerusalem with him This may be explained in two ways. Either the people were roused, in a tumultuous manner, by the novelty of the occurrence, though the glad tidings of a king who had been born to them were cordially welcomed. Or the people, accustomed to distresses, and rendered callous by long endurance, dreaded a change which might introduce still greater calamities. For they were so completely worn down, and almost wasted, by continued wars, that their wretched and cruel bondage appeared to them not only tolerable, but desirable, provided it were accompanied by peace. This shows how little they had profited under God's chastisements: for they were so benumbed and stupified, that the promised redemption and salvation almost stank [3] in their nostrils. Matthew intended, I have no doubt, to express their ingratitude, in being so entirely broken by the long continuance of their afflictions, as to throw away the hope and desire of the grace which had been promised to them.

1 - "Lusoria;" alluding to the phrase used by Seneca and others, lusoria fulmina, "harmless thunderbolts."

3 - "Quodammodo foeteret,"

Had heard these things - Had heard of their coming, and of the star, and of the design of their coming.
He was troubled - Herod had obtained the kingdom by great crimes, and by shedding much blood. He was therefore easily alarmed by any remarkable appearances; and the fact that this star appeared, and that it was regarded as proof that a King of the Jews was born, alarmed him. Besides, it was a common expectation that the Messiah was about to appear, and he feared that his reign was about to come to an end. He therefore began to inquire in what way he might secure his own safety and the permanency of his government.
All Jerusalem - The people of Jerusalem, and particularly the friends of Herod. There were many in Jerusalem to whom the coming of the Messiah would be a matter of joy; but all of Herod's friends would doubtless be alarmed at his coming.

When Herod - heard these things, he was troubled - Herod's consternation was probably occasioned by the agreement of the account of the magi, with an opinion predominant throughout the east, and particularly in Judea, that some great personage would soon make his appearance, for the deliverance of Israel from their enemies; and would take upon himself universal empire.
Suetonius and Tacitus, two Roman historians, mention this. Their words are very remarkable: -
Percrebuerat Oriente toto, vetus et constans opinio, esse in fatis, ut eo tempore Judaea profecti rerum potirentur. Id de imperatare Romano, quantum eventu postea predictum patuit, Judaei ad se trahentes, rebellarunt.
Sueton. Vesp.
"An ancient and settled persuasion prevailed throughout the east, that the fates had decreed some to proceed from Judea, who should attain universal empire. This persuasion, which the event proved to respect the Roman emperor, the Jews applied to themselves, and therefore rebelled."
The words of Tacitus are nearly similar: -
Pluribus persuasio inerat, antiquis sacerdotum literis contineri, eo ipso tempore fore, ut valesceret Oriens, profectique Judaea rerum potirentur. Quae ambages Vespasianum ac Titum praedixerant.
"Many were persuaded, that it was contained in the ancient books of their priests, that at that very time the east should prevail: and that some should proceed from Judea and possess the dominion. It was Vespasian and Titus that these ambiguous prophecies predicted."
Histor. v.

When Herod the king had heard [these things], he was (c) troubled, and all Jerusalem with him.
(c) Was much moved, for he was a foreigner, and became ruler by force; and the Jews were troubled; for wickedness is mad and raging.

When Herod the king had heard these things,.... That is, the report made by the wise men of the appearance of an unusual star, and of the birth of the king of the Jews, which they affirmed with all certainty, without any hesitation,
he was troubled, and all Jerusalem with him. Herod was troubled, his mind was disturbed and made uneasy, fearing he should be deposed, and lose his kingdom, to which he knew he had no just right and claim, being a foreigner; and "all Jerusalem", i.e. all the inhabitants of Jerusalem, who heard of this, were also troubled, and showed a concern at it with him; either feignedly, as knowing his jealousy, suspicion and cruelty; or in reality, because of tumults, commotions and wars, they might fear would arise upon this, having lost the true notion of the Messiah, as a spiritual king, saviour and redeemer. And hereby was fulfilled, in part, the famous prophecy in Genesis 49:10 according to the sense of one (w) of the Targumists on it, who paraphrases it after this manner;
"Kings and governors shall not cease from the house of Judah, nor scribes, who teach the law, from his seed, until the time that the king Messiah, the least of his sons, comes, "and because of him", , "the people shall melt."''
that is, they shall be distressed and troubled, their hearts shall melt like wax within them; which was their present case, though perhaps the paraphrast may design the Gentiles.
(w) Jonathan ben Uzziel in loc.

When Herod the king had heard these things, he was troubled--viewing this as a danger to his own throne: perhaps his guilty conscience also suggested other grounds of fear.
and all Jerusalem with him--from a dread of revolutionary commotions, and perhaps also of Herod's rage.

Herod . . . was troubled. The trouble of Herod is easily accounted for. He was a usurper. This news seemed to portend a legitimate king, a rival for the throne, around whom the Jewish nation would rally.
All Jerusalem with him. The capital was in commotion. It was the seat of Herod's power, and his staunchest supporters were there.
