These princes were four:
(1) Nergal, Sharezer, i. e., Nirgal-sar-usur (May Nergal protect the king);
(2) Samgar-Nebo (Be gracious, O Nebo);
(3) Sarsechim. No explanation is given at present of this name. He was Rab-saris, i. e., chief of the eunuchs (2 Kings 18:17 note).
(4) another Nergal-sharezer, who was Rab-mag, i. e., chief of the Magians. He is known in history as Neriglissar, the son-in-law of Nebuchadnezzar, and probably his vicegerent during his seven years of madness. Two years after his death Neriglissar murdered Evil-Merodach, Nebuchadnezzars son, and seized the crown, but after a reign of four years was slain in battle against Cyrus, when disputing with him the crown of Media. See Daniel 5:1 note.
The middle gate - Probably that which separated the city of Zion from the lower town.
