Acts 12:3-5

³The Jewish leaders told Herod that they were happy for him to kill James, so Herod told his soldiers to grab Peter too. They grabbed him at the time for the Jewish people to have their ceremony where they ate flat damper.

⁴Herod thought, “I will wait until the end of that ceremony, then I will judge Peter and kill him.” So they put Peter in jail, and Herod told 16 soldiers to guard him there. Those soldiers were in 4 little mobs, with 4 soldiers in each little mob.

⁵Peter stayed there in jail, and the other Christians prayed for him a lot.
