Acts 12:5-7 Holman Christian Standard Bible (HCSB)
5 So Peter was kept in prison, but prayer was being made earnestly to God for him by the church.
6 On the night before Herod was to bring him out for execution, Peter, bound with two chains, was sleeping between two soldiers, while the sentries in front of the door guarded the prison. 7 Suddenly an angel of the Lord appeared, and a light shone in the cell. Striking Peter on the side, he woke him up and said, “Quick, get up!” Then the chains fell off his wrists.
