20 Now Herod was very angry with the people of Tyre and Sidon. So they sent a delegation to make peace with him because their cities were dependent upon Herod's country for food. The delegates won the support of Blastus, Herod's personal assistant, 21 and an appointment with Herod was granted. When the day arrived, Herod put on his royal robes, sat on his throne, and made a speech to them. 22 The people gave him a great ovation, shouting, "It's the voice of a god, not of a man!" 23 Instantly, an angel of the Lord struck Herod with a sickness, because he accepted the people's worship instead of giving the glory to God. So he was consumed with worms and died.

(Read Acts 12:20-25)
Many heathen princes claimed and received Divine honours, but it was far more horrible impiety in Herod, who knew the word and worship of the living God, to accept such idolatrous honours without rebuking the blasphemy. And such men as Herod, when puffed with pride and vanity, are ripening fast for signal vengeance. God is very jealous for his own honour, and will be glorified upon those whom he is not glorified by. See what vile bodies we carry about with us; they have in them the seeds of their own dissolution, by which they will soon be destroyed, whenever God does but speak the word. We may learn wisdom from the people of Tyre and Sidon, for we have offended the Lord with our sins. We depend on him for life, and breath, and all things; it surely then behoves us to humble ourselves before him, that through the appointed Mediator, who is ever ready to befriend us, we may be reconciled to him, lest wrath come upon us to the utmost.
