After arresting him, he put him in prison, handing him over to be guarded by four squads of four soldiers each. Herod intended to bring him out for public trial after the Passover.15
So Peter was kept in prison, but the church was earnestly praying to God for him.26
The night before Herod was to bring him to trial, Peter was sleeping between two soldiers, bound with two chains,3 and sentries stood guard at the entrance.
