Acts 12:25

And Barnabas and Saul returned from Jerusalem when they had fulfilled their ministry, and took with them John, whose surname was Mark.

Luke here adds a few words in regard to the cause of the death of Herod Agrippa I to round out the narrative. Herod was king of Palestine and of all the provinces south of Syria, but Phoenicia, which belonged to Syria, was a thorn in his side. Whether it was merely a case of commercial warfare or of jealousy on account of some other advantage which the maritime province enjoyed, Herod was engaged in a violent quarrel with them, which might easily have culminated in some sort of bitter clash. But the cities along the coast could not afford to have such a condition obtain, since they received their grain and other foods from Palestine. Therefore they waited on him unanimously, having instructed their delegates to that effect. In addition, they managed to gain the good will of Blastus, the chamberlain, or minister of finance, of Herod, securing his good will in using his good offices for maintaining peace and removing the cause of the feud. It is by no means outside of the pale of the story or beyond reasonable possibility to suppose that bribery was resorted to, and that the king's good will was gained in this manner. Herod was highly pleased with his success in this matter, and so on a certain set day he received the embassy of the Phoenicians, arrayed in the splendor of all his royal garments and sitting upon his throne, from which he formally addressed the commissioners and the assembled people. And the entire multitude of the people, knowing that flattery will obtain in the case of a tyrant what reasonable arguments should in the case of a sensible person, cried out: The voice of a god and not of a man! Instead of reproving the flatterers with all signs of horror, the tyrant was highly pleased with their shouting. And therefore the punishment of God struck Herod at once. An angel of the Lord, as minister of the divine will, smote him for taking the glory away from God and thus becoming guilty of the basest blasphemy. He was seized with violent pains in the abdomen, caused by the fact that he was eaten by worms, lingered in great agony for five days, and then breathed his last. That was a visible judgment of God upon the persecutor of the Church. And many a tyrant since has felt the heavy hand of the Lord on account of his blasphemy, and has had a terrible end. But the death of Herod removed the pressure upon the congregations everywhere. The Word of God grew. spread, and multiplied. The removal of this obstacle gave a new impetus to the preaching of the Gospel. And Barnabas and Saul, having carried out their commission and fulfilled their service of mercy by transmitting the money that had been entrusted to them for the use of the sufferers, with the sincere good wishes of the congregation at Antioch, returned from Jerusalem, taking along with them John, with the surname Mark. He was their companion on this journey back to Antioch, and incidentally received some training in actual ministerial work, always of value to a young man that intends to enter the service of the Lord as a preacher.

Summary

Herod has James beheaded and Peter imprisoned, the latter being delivered by an angel of the Lord, while the king is stricken by God; whereupon the Church again enters upon a season of prosperity.
