Acts 12:1-7

1 At that time Herod the king laid his hands on some of those of the assembly to do them hurt,
2 and slew James, the brother of John, with the sword.
3 And seeing that it was pleasing to the Jews, he went on to take Peter also: (and they were the days of unleavened bread:)
4 whom having seized he put in prison, having delivered him to four quaternions of soldiers to keep, purposing after the passover to bring him out to the people.
5 Peter therefore was kept in the prison; but unceasing prayer was made by the assembly to God concerning him.
6 And when Herod was going to bring him forth, that night Peter was sleeping between two soldiers, bound with two chains, and guards before the door kept the prison.
7 And lo, an angel of [the] Lord came there, and a light shone in the prison: and having smitten the side of Peter, he roused him up, saying, Rise up quickly. And his chains fell off his hands.
