Acts 22:30

Verse 30. On the morrow. After he had arrested Paul. Paul was still a prisoner; and if suffered to go at liberty among the Jews, his life would have been in danger. And commanded the chief priests, etc. Summoned a meeting of the sanhedrim, or great council of the nation. He did this, as he was prevented from scourging Paul, in order to know what he had done, and that he might learn from the Jews themselves the nature of the charge against him. This was necessary for the safety of Paul, and for the ends of justice. This should have been done without any attempt to torture him in order to extort a confession. And brought Paul down. From the elevated castle or tower of Antonia.
