Acts 12:18-23 (NIV)
18 In the morning, there was no small commotion among the soldiers as to what had become of Peter. 19 After Herod had a thorough search made for him and did not find him, he cross-examined the guards and ordered that they be executed.
Then Herod went from Judea to Caesarea and stayed there. 20 He had been quarreling with the people of Tyre and Sidon; they now joined together and sought an audience with him. After securing the support of Blastus, a trusted personal servant of the king, they asked for peace, because they depended on the king’s country for their food supply.
21 On the appointed day Herod, wearing his royal robes, sat on his throne and delivered a public address to the people. 22 They shouted, “This is the voice of a god, not of a man.” 23 Immediately, because Herod did not give praise to God, an angel of the Lord struck him down, and he was eaten by worms and died.
