Acts 12:1,2 - Joseph Benson’s Commentary on the Old and New Testaments

Now about that time When Saul and Barnabas were preparing to set out to Jerusalem, to carry thither what had been collected by the Christians at Antioch; Herod stretched forth his hands to vex certain of the church So wisely did God mix rest and persecution, in due time and measure succeeding each other. This was Herod Agrippa, as the Syriac version expressly names him, the former being his Syrian, and the latter his Roman name. He was the grandson of Herod the Great, nephew to Herod Antipas, who beheaded John the Baptist, brother to Herodias, and father to that Agrippa before whom St. Paul afterward made his defence. Caligula made him king of the tetrarchy of his uncle Philip, to which he afterward added the territories of Antipas. Claudius made him also king of Judea, and added thereto the dominions of Lysanias. And he killed James the brother of John Thus was the prediction of our Lord fulfilled, that James should drink of his cup, (Matthew 20:23,) and thus one of the brothers went to God the first, the other the last of the apostles. It is a just observation of a judicious writer, that “this early execution of one of the apostles, after our Lord's death, would illustrate the courage of the rest in still going on with their ministry, as it would evidently show, that even all their miraculous powers did not secure them from dying by the sword of their enemies.”
