Luke always calls the king, Herod, which was the family name, while Josephus calls him by his given name Agrippa. He is known to us under the name of Herod Agrippa I. It seems strange that Eusebius should not have known that he bore the two names, Herod Agrippa, instead of expressing doubt in the matter, as he does. In the heading of the chapter he gives the king both names, without intimating that he entertained any uncertainty in the matter.
