“And all the princes of the king of Babylon came in, and sate in the middle gate, euen Nergal-Sharezer, Samgar-Nebo, Sarsechim, Rabsaris, Nergal-Sharezer, Rabmag, with all the residue of the princes of the king of Babylon.”
1611 King James Version (KJV)
39:3 The middle gate - The city was encompassed with two walls, before they came to the wall of the temple; the gate in the inner wall is supposed to have been that which is called the middle gate. They would not at first venture farther, 'till they might without hazarding their persons.
