'Session' in the Bible

Let them exalt him also in the congregation of the people, and praise him in the session of the elders.

He went down to the chamber of the royal secretary in the king's palace and found all the court officials in session there. Elishama the royal secretary, Delaiah son of Shemaiah, Elnathan son of Achbor, Gemariah son of Shaphan, Zedekiah son of Hananiah, and all the other officials were seated there.

“A river of fire was flowingAnd coming out from before Him;A thousand thousands were attending Him,And ten thousand times ten thousand were standing before Him;The court was seated,And the books were opened.

So if Demetrius and the craftsmen who are with him have a case against anyone, the courts are in session, and there are proconsuls. Let them bring charges against one another.
