John Wesley on Acts 12:21

And on a set day - Which was solemnized yearly, in honour of Claudius Cesar; Herod, arrayed in royal apparel - In a garment so wrought with silver, that the rays of the rising sun striking upon, and being reflected from it, dazzled the eyes of the beholders. The people shouted, It is the voice of a god - Such profane flattery they frequently paid to princes. But the commonness of a wicked custom rather increases than lessens the guilt of it.
