Acts 12:3-5

³And when he saw that this was pleasing to the Jews he went on to take Peter in addition. This was at the time of the feast of unleavened bread.

⁴And having taken him, he put him in prison, with four bands of armed men to keep watch over him; his purpose being to take him out to the people after the Passover.

⁵So Peter was kept in prison: but the church made strong prayer to God for him.
