The Acts 12:4-6

After Herod arrested Peter, he put him in jail and handed him over to be guarded by 16 soldiers. Herod planned to bring Peter before the people for trial after the Passover Feast. So Peter was kept in jail. But the church kept on praying to God for him. The night before Herod was to bring him to trial, Peter was sleeping. He was between two soldiers, bound with two chains. Other soldiers were guarding the door of the jail.
