Matthew Poole and continuators on Acts 12:21

21 And upon a set day, Herod arayed in royal apparel, sat upon his throne, and made an oration unto them.

This was (says Iosephus cap. 19. lib. 7.) the second day of the sports or games, which Herod had instituted in honour of the Emperor Claudius; or it may be such a day as Herod had appointed to determine the difference in, betwixt him and the Tyrians.

Such, saith Iosephus, as were made of Silver, woven with extraordinary art, and did reflect strangly the beams of the Sun shining upon it: An elevated place, from whence he might the better be seen and heard.
