Forthwith he smote him. As, before, the angel was a minister of God's grace in the delivery of Peter, so now he taketh vengeance upon Herod. And God doth sometimes use the ministry of angels in heaven in punishing; but sometimes he maketh the devils as hangmen, by whose hand he executeth his judgments. And this doth he as well toward his faithful servants as toward the reprobate. Saul was troubled and vexed by Satan, (1 Samuel 16:14) but the same did also befall holy Job, (Job 1:12; 2:7.) In the Psalms, the punishments wherewith God doth chasten the wicked are attributed to the evil angels; yet we see how the angel which had the government of the safety of the Church smiteth the Egyptians in the first-begotten, (Exodus 12:29;) although the Scripture calleth the wicked spirits God's spirits, because they are obedient to his commandment, though full sore against their will. But where the epithet evil is not added, as in this place, we must understand the angel which doth willingly obey God, and yet the shape of the owl, whereof Josephus maketh mention, did rather serve to figure the devil than an heavenly angel. Furthermore, I dare not affirm for a surety what manner of disease that was. The word which Luke useth doth signify that he was eaten up of worms. Many conjecture that it was a lousy disease. This is certain, that even when he was yet alive he was corrupt with stink and rottenness, so that he was, as it were, a living carcass. So that he was not only vexed with cruel torments, but also made a laughing-stock to all men, and of all men reviled. For God intended to make choice of a kind of punishment wherewith he might repress the cruelty of a proud man with extreme ignominy. If he had been overcome of some great and valiant army, and had been brought to poverty, the judgment of God had not been so marked; and this had been an honest and princely chastisement; [1] but forasmuch as he abhorreth lice and worms, and this filthiness cometh out of his body, which doth kill him by eating him up, he is handled according to his deserts. In like sort Pharaoh, forasmuch as he did so oft exalt himself against God with untamed pride, he was not orderly assailed by some prince that did border upon him, but locusts and caterpillars were God's warriors [soldiers] to make war against him, (Exodus 8:17, 24;) for the more proudly a man exalteth himself, the more doth he deserve to be cast doom of God into the lowest hell with shame and reproach. This is the reason why he set this reigned god Herod to be eaten up of worms, which he was at length enforced to grant, when he said, "Behold me, whom ye saluted as a god; I die miserable." Such a manifest example of horrible vengeance in a king's person ought to terrify us not a little from presuming to take to ourselves more than we ought; and that we do not suffer ourselves to be made drunk with the false commendation and flattery of men as with deadly poison. Because he gave not the glory to God. He is condemned of sacrilege, not only because he suffered himself to be called God, but because, forgetting himself, he took to himself the honor due to God. We do not read that the king of Babylon was thus extolled; and yet the prophet upbraideth to him that he went about to make himself equal with God, (Isaiah 14:13, 14.) Therefore this sacrilege is a common fault in all proud men, because, by taking to themselves more than they ought, they darken the glory of God; and so, like giants, so much as ever they are able, they endeavor to pluck God out of his seat. Howsoever, they do not usurp the title of God, neither openly boast with their mouth that they are gods; yet because they take to themselves that which is proper to God, they desire to be, and to be accounted gods, having brought him under, furthermore, the prophet pointeth out the beginning of this evil in one word, when he bringeth in Nebuchadnezzar speaking on this wise, "I will go up," (Isaiah 14:13.) Wherefore there is but one remedy, if every one keep himself in that degree wherein he is placed. Let those who are base and castaways [in a humble station] not desire to climb higher; let kings, and those who are above others, remember that they are mortal, and let them modestly submit their highness to God. And we must note, that it is not enough if men give to God only half the honor which is due to him, who challengeth all that wholly which is his own; if they submit themselves but in part, whom he will have to be thoroughly humbled. Now, forasmuch as the Scripture despoileth us quite of all praise of wisdom, virtue, and righteousness, there is no one of us that can take to himself the least jot of glory without sacrilegious robbing of God. And it is a wonder that, seeing the Scripture pronounceth that all those make, as it were, open war against God which exalt themselves; and we do all grant that that cannot be done without our overthrow, [destruction;] the greatest part of men runneth, notwithstanding, headlong with furious boldness unto their own destruction; for there is scarce one of an hundred who, being mindful of his condition, doth leave to God his glory undiminished.

Footnotes

1 - "Liberalis et regia castigatio," a dignified and royal chastisement.

And immediately the angel of the Lord - Diseases and death axe in the Scriptures often attributed to an angel. See 2-Samuel 24:16; 1-Chronicles 21:12, 1-Chronicles 21:15, 1-Chronicles 21:20, 1-Chronicles 21:27; 2-Chronicles 32:21. It is not intended that there was a miracle in this case, but it certainly is intended by the sacred writer that his death was a divine judgment on him for his receiving homage as a god. Josephus says of him that he "did neither rebuke them the people nor reject their impious flattery. A severe pain arose in his belly, and began in a most violent manner. And when he was quite worn out by the pain in his belly for five days, he departed this life, in the 54th year of his age, and the 7th year of his reign." Josephus does not mention that it was done by an angel, but says that when he looked up, he saw an owl sitting on a rope over his head, and judging it to be an evil omen, he immediately became melancholy, and was seized with the pain.
Because he gave not God the glory - Because he was willing to receive the worship due to God. It was the more sinful in him as he was a Jew, and was acquainted with the true God, and with the evils of idolatry. He was proud, and willing to be flattered, and even adored. He had sought their applause; he had arrayed himself in this splendid manner to excite admiration; and when they carried it even so far as to offer divine homage, he did not reject the impious flattery, but listened stir to their praises. Hence, he was judged; and God vindicated his own insulted honor by inflicting severe pains on him, and by a most awful death.
And he was eaten of worms - The word used here is not found elsewhere in the New Testament. A similar disease is recorded of Antiochus Epiphanes, in the Apocrypha, 2 Macc. 9:5, "But the Lord Almighty, the God of Israel, smote him with an invisible and incurable plague; for a pain in the bowels that was remediless came upon him, and sore torments of the inner parts Acts 12:9, so that worms rose up out of the body of this wicked man," etc. Probably this was the disease known as morbus pedicularis. It is loathsome, offensive, and most painful. See the death of Antiochus Epiphanes described in 2 Macc. 9. With this disease also Herod the Great, grandfather of Herod Agrippa, died (Josephus, Antiq., book 17, chapter 6, section 5). Such a death, so painful, so sudden, and so loathsome, was an appropriate judgment on the pride of Herod. We may here learn:
(1) That sudden and violent deaths are often acts of direct divine judgment on wicked people.
(2) that people, when they seek praise and flattery, expose themselves to the displeasure of God. His glory he will not give to another, Isaiah 42:8.
(3) that the most proud, and mighty, and magnificent princes have no security of their lives. God can in a moment - even when they are surrounded by their worshippers and flatterers - touch the seat of life, and turn them to loathsomeness and putrefaction. What a pitiable being is a man of pride receiving from his fellow-men that homage which is due to God alone! See Isaiah. 14.
(4) pride and vanity, in any station of life, are hateful in the sight of God. Nothing is more inappropriate to our situation as lost, dying sinners, and nothing will more certainly meet the wrath of heaven.
(5) we have here a strong confirmation of the truth of the sacred narrative. In all essential particulars Luke coincides in his account of the death of Herod with Josephus. This is one of the many circumstances which show that the sacred Scriptures were written at the time when they professed to be, and that they accord with the truth. See Lardner's Credibility, part 1, chapter 1, section 6.

The angel of the Lord smote him - His death was most evidently a judgment from God.
Because he gave not God the glory - He did not rebuke his flatterers, but permitted them to give him that honor that was due to God alone. See on Acts 12:21 (note).
And was eaten of worms - Whether this was the morbus pedicularis, or whether a violent inflammation of his bowels, terminating in putrefaction, did not actually produce worms, which, for several days, swarmed in his infected entrails, we cannot tell. It is most likely that this latter was the case; and this is at once more agreeable to the letter of the text, and to the circumstances of the case as related by Josephus.
And gave up the ghost - That is, he died of the disorder by which he was then seized, after having lingered, in excruciating torments, for five days, as Josephus has stated. Antiochus Epiphanes and Herod the Great died of the same kind of disease. See the observations at the end of Acts 1:26 (note) relative to the death of Judas.

(11) And immediately the angel of the Lord smote him, because he (e) gave not God the glory: and he was eaten of worms, and gave up the ghost.
(11) God resists the proud.
(e) Josephus records that this king did not repress the flatterer's tongues, and therefore at his death he complained and cried out about their empty praise.

And immediately the angel of the Lord smote him,.... With a disease after mentioned; this angel, according to Josephus, appeared in the form of an owl; for he says, that a little after (the shout of the people) the king looked up, and saw an owl sitting upon a rope over his head; whom he immediately understood to be an angel, or messenger of evil things to him, as it had been before of good things; for it seems by the same historian (s), that when he was bound by the order of Caligula, he saw an owl sitting on that tree, on which he leaned; when a certain German predicted, that things would in a short time be changed with him, and he should be advanced to great honour; but remember, says he, whenever you see that bird again, you will die within five days. Eusebius (t), out of Josephus, makes no mention of the owl, but relates it thus; that a little after (the oration and the salutation of the people) the king looked up, and saw an angel sitting over his head, whom he immediately understood to be the cause of evil things to him, as he had formerly been of good: the reason of the angel's smiting him was,
because he gave not glory to God; or as the Jewish historian says, because he reproved not the flatterers, nor rejected their impious flattery, but tacitly took that to himself, which belonged to God:
and he was eaten of worms: Beza's most ancient copy adds, "while he was alive"; Josephus only makes mention of pains in his belly, but these were occasioned by the gnawing of the worms: this was accounted by the Jews a very accursed death; they say (u), that the spies which brought an ill report on the good land, died this death: their account is this, that
"their tongues swelled and fell upon their navels, and worms came out of their tongues and went into their navels, and out of their navels they went into their tongues,''
of this death died many tyrants, oppressors, and persecutors! as Antiochus,
"So that the worms rose up out of the body of this wicked man, and whiles he lived in sorrow and pain, his flesh fell away, and the filthiness of his smell was noisome to all his army.'' (2 Maccabees 9:9)
and Herod the great, the grandfather of this, according to Josephus (w); and Maximianus Galerius, according to Eusebius (x), and many others:
and gave up the ghost: not directly, but five days after, as Josephus relates, in the fifty fourth year of his age, and when he had reigned seven years; but before he died, and as soon as he was smitten, he turned to his friends and said, I your God am obliged to depart this life, and now fate reproves the lying words you have just now spoke of me; and I who was called immortal by you, am led away to die, with more, as related by Josephus: by such a token as this, a man was discovered to be a murderer with the Jews; for so they say (y), that
"out of the beheaded heifer went a vast number of worms, and went to the place where the murderer was, and ascended upon him, and then the sanhedrim laid hold on him and condemned him.''

The angel of the Lord smote him. Josephus says he lingered five days in great agony. This harmonizes with Luke's account.
He was eaten of worms. Josephus says he was taken with abdominal pains; Luke explains the cause. The disease is by no means unknown. Many cases of death from the same cause are on record. Among others the Emperor Galerius, the predecessor of Constantine the Great, so died.

And immediately - God does not delay to vindicate his injured honour; an angel of the Lord smote him - Of this other historians say nothing: so wide a difference there is between Divine and human history! An angel of the Lord brought out Peter; an angel smote Herod. Men did not see the instruments in either case. These were only known to the people of God. Because he gave not glory to God - He willingly received it to himself, and by this sacrilege filled up the measure of his iniquities. So then vengeance tarried not. And he was eaten by worms, or vermin - How changed! And on the fifth day expired in exquisite torture. Such was the event! The persecutor perished, and the Gospel grew and multiplied.
