Acts 12:3-5

³And seeing that it pleased the Jews, he proceeded to apprehend Peter also; (then were the days of unleavened bread;)

⁴and he seized him and put him in prison, and delivered him to four quaternions of soldiers to keep him; intending after the passover to bring him forth to the people.

⁵Peter therefore was kept guarded in prison; but earnest prayer was made by the church to God in his behalf.
