Agrippa I also known as Herod Agrippa or simply Herod (10 BCE – 44 CE), King of the Jews, was the grandson of Herod the Great, and son of Aristobulus IV and Berenice. His original name was Marcus Julius Agrippa, so named in honour of Roman statesman Marcus Vipsanius Agrippa, and he is the king named Herod in the Acts of the Apostles, in the Bible, “Herod (Agrippa)” (Ἡρώδης Ἀγρίππας). He was, according to Josephus, known in his time as “Agrippa the Great.”
His death is mentioned in Acts 12 in the words “an angel of the Lord struck him, because he did not give glory to God. And he was eaten by worms and died.” Modern scholars believe he might have died of Fournier’s gangrene, a kidney disease, the same that also killed his grandfather Herod the Great (See CNN article).
Luke: Acts 12:20-23
Now Herod had been very angry with the people of Tyre and Sidon; but they came to him with one accord, and having made Blastus the king’s personal aide their friend, they asked for peace, because their country was supplied with food by the king’s country. So on a set day Herod, arrayed in royal apparel, sat on his throne and gave an oration to them. And the people kept shouting, “The voice of a god and not of a man!” Then immediately an angel of the Lord struck him, because he did not give glory to God. And he was eaten by worms and died.
Josephus: Antiquities 19:8:2
Now when Agrippa had reigned three years over all Judea, he came to the city Cesarea, which was formerly called Strato’s Tower; and there he exhibited shows in honor of Caesar, upon his being informed that there was a certain festival celebrated to make vows for his safety. At which festival a great multitude was gotten together of the principal persons, and such as were of dignity through his province. On the second day of which shows he put on a garment made wholly of silver, and of a contexture truly wonderful, and came into the theater early in the morning; at which time the silver of his garment being illuminated by the fresh reflection of the sun’s rays upon it, shone out after a surprising manner, and was so resplendent as to spread a horror over those that looked intently upon him; and presently his flatterers cried out, one from one place, and another from another, (though not for his good), that he was a god; and they added, “Be thou merciful to us; for although we have hitherto reverenced thee only as a man, yet shall we henceforth own thee as superior to mortal nature.” Upon this the king did neither rebuke them, nor reject their impious flattery. But as he presently afterward looked up, he saw an owl sitting on a certain rope over his head, and immediately understood that this bird was the messenger of ill tidings, as it had once been the messenger of good tidings to him; and fell into the deepest sorrow. A severe pain also arose in his belly, and began in a most violent manner. He therefore looked upon his friends, and said, “I, whom you call a god, am commanded presently to depart this life; while Providence thus reproves the lying words you just now said to me; and I, who was by you called immortal, am immediately to be hurried away by death. But I am bound to accept of what Providence allots, as it pleases God; for we have by no means lived ill, but in a splendid and happy manner.” When he said this, his pain was become violent. Accordingly he was carried into the palace, and the rumor went abroad every where, that he would certainly die in a little time. But the multitude presently sat in sackcloth, with their wives and children, after the law of their country, and besought God for the king’s recovery. All places were also full of mourning and lamentation. Now the king rested in a high chamber, and as he saw them below lying prostrate on the ground, he could not himself forbear weeping. And when he had been quite worn out by the pain in his belly for five days, he departed this life, being in the fifty-fourth year of his age, and in the seventh year of his reign….
