Acts 5:19

God useth the ministry of angels, though he might otherwise do what pleaseth him. An angel rolled away the stone from the door of the sepulchre. Angels ministered to Christ, Matthew 4:11; and are all ministering spirits, sent forth to master for them who shall be heirs of salvation, Hebrews 1:14; and encamp round about them that fear God, Psalms 34:7. Opened the prison doors; and shut them again, after that the apostles were gone out, as appears Acts 5:23.
