Acts 12:2-5

Anderson(i) 2 And he slew with the sword James the brother of John. 3 And when he saw that it pleased the Jews, he apprehended Peter also. Those were the days of unleavened bread. 4 And when he had apprehended him, he put him in prison, and delivered him to four tetrads of soldiers to guard him, intending to bring him out to the people after the passover. 5 Therefore, Peter was kept in prison; but fervent prayer to God was made for him by the church.
