3When he saw that it pleased the Judeans, he proceeded to seize Peter also. This was during the days of unleavened bread.
4When he had arrested him, he put him in prison and delivered him to four squads of four soldiers each to guard him, intending to bring him out to the people after the Passover.
5Peter therefore was kept in the prison, but constant prayer was made by the assembly to God for him.
6The same night when Herod was about to bring him out, Peter was sleeping between two soldiers, bound with two chains. Guards in front of the door kept the prison.
7And behold, an angel of the Lord stood by him, and a light shone in the cell. He struck Peter on the side and woke him up, saying, “Stand up quickly!” His chains fell off his hands.
