Acts 5:19

19-21. When they were all seized and cast into prison together, the apostles could but expect that they would now feel the entire weight of the wrath which was treasured up against them. (19) "But an angel of the Lord opened the prison doors in the night, and led them forth, and said, (20) Go stand in the temple, and speak to the people all the words of this life. (21) And having heard this they entered into the temple early in the morning, and taught. But the high priest came, and those who were with him, and called together the Sanhedrim, and all the eldership of the children of Israel, and sent into the prison to have them brought." The apostles were already in the temple, teaching the early worshipers as if nothing unusual had occurred, when the Sanhedrim met and sent to the prison for them.
