There fell a voice from heaven: this made the judgment more remarkable, and argued the sin more provoking, and the anger of God more just against him. Sudden judgments are most dreadful; whereof we have many instances, as in Herod, Elymas, Ananias and Sapphira, &c.: this voice was from God; it also was loud, and clearly perceived by the king and them about him, which the dream intimated more obscurely. Not the kingdom, but the administration of the government, was transferred to others.
