Herod Agrippa I in Fausset's Bible Dictionary
5. HEROD AGRIPPA I. Son of Aristobulus Herod the Great's son) and Berenice. Imprisoned by Tiberius for an unguarded speech. Caius Caligula, A.D. 37, on his accession set him free, and gave him the governments formerly held by the tetrarchs Philip and Lysanias, Abilene, etc., with the title of "king" (Acts 12:1). Galilee and Peraea were added to his dominions on the exile of Herod ANTIPAS (see above), whom, notwithstanding the kindnesses he formerly when in difficulties received from him, Agrippa supplanted by intrigues at Rome. By services to Claudius, Caligula's successor, he secured in return the addition of Judaea and Samaria, so that now his kingdom equaled that of Herod the Great. Unlike his predecessors he strictly kept the law. A legend states that once he burst into tears on reading in a public service Deuteronomy 17:15, on which the Jews exclaimed, "Be not distressed, thou art our brother," namely, by half-descent from the Hasmonaeans. It was on his entreaty at the risk of his interest and life that Caligula desisted from his attempt to set up his statue in the temple, which so engrossed the Jews that for a time they let the Christians alone (Acts 9:31). To "please the Jews" he slew James the brother of John, and imprisoned Peter with the intention of bringing him forth to the people for execution after the Passover ("Easter".) Love of popularity was his ruling principle, to which his ordinary humanity was made to give way. Self seeking vanity led him to design Peter's death, but the issue was his own death. The church's "prayer without ceasing" (Isaiah 62:6- 7; Luke 18:7) saved Peter, whereas the church's Lord avenged His own and her cause on the church's persecutor. In the fourth year of his reign over the whole kingdom (A.D. 44) he attended games at Caesarea "in behalf of the emperor's safety" (possibly on his return from Britain), according to Josephus (Ant. 19:8). When he appeared in the theater in a robe all of silver stuff which shone in the morning light, his flatterers saluted him as a god, and suddenly he was afflicted with a terrible pain in the bowels, of which he died in five days, in the 54th year of his age. The sacred writer unveils the unseen world in his account, which Josephus so remarkably confirms. The authorities of Tyre and Sidon offended him, "but came with one accord and, having made Blastus the king's chamberlain their friend, desired peace because their country" was dependent on the king's country for grain, etc. (1 Kings 5:9; 1 Kings 5:11; Ezekiel 27:17). Then upon a set day" Herod arrayed in royal apparel sat upon his throne and made an oration. And the people gave a shout, saying It is the voice of a god and not of a man. And immediately the angel of the Lord smote him, because he gave not God the glory; and he was eaten of worms and gave up the ghost. But the word of God (which he bad thought to stifle) grew and multiplied." So Belshazzar (Daniel 5); "pride teeth before destruction" (Proverbs 16:18). Josephus states that Herod said in his pain, "I whom you call a god am ordered to depart this life immediately. Providence thus instantly reproves the lying words you just now addressed to me, and I who was by you called immortal am immediately to be hurried away by death." Thus fell he whom the world called Agrippa the Great! a monument to warn proud men, "Woe unto him that striveth with his Maker! Let the potsherd strive with the potsherds of the earth" (Isaiah 45:9).Read More about Herod Agrippa I in Fausset's Bible Dictionary
