Acts 12:5 ASV

³  And when he saw that it pleased the Jews, he proceeded to seize Peter also. And `those' were the days of unleavened bread.

⁴  And when he had taken him, he put him in prison, and delivered him to four quaternions of soldiers to guard him; intending after the Passover to bring him forth to the people.

⁵  Peter therefore was kept in the prison: but prayer was made earnestly of the church unto God for him.

⁶  And when Herod was about to bring him forth, the same night Peter was sleeping between two soldiers, bound with two chains: and guards before the door kept the prison.

⁷  And behold, an angel of the Lord stood by him, and a light shined in the cell: and he smote Peter on the side, and awoke him, saying, Rise up quickly. And his chains fell off from his hands.
