Acts 12:3-7

³After he saw that this pleased the Jews, he proceeded to arrest Peter also. That was during the days of unleavened bread.

⁴After arresting him, he put him in prison, assigning him over to four squads of soldiers to guard him; he was intending to bring him to the people after the Passover.

⁵So Peter was kept in the prison, but prayer was made earnestly to God for him by those in the church.

⁶On the night before Herod was going to bring him out for trial, Peter was sleeping between two soldiers, bound with two chains, while guards in front of the door were keeping watch over the prison.

⁷Behold, an angel of the Lord suddenly appeared by him, and a light shone in the prison cell. He struck Peter on the side and woke him and said, “Get up quickly,” and his chains fell off his hands.
