Rabmag
Fausset's Bible Dictionary [1]
Jeremiah 39:3; Jeremiah 39:13. (See Nergal SHAREZER.) Probably Magis not Magus or Magusu ("the Magi") of the Behistun inscription; the Magi had no standing in Neriglissar's time at Babylon. Εmga means "priest," so Rabmag is "chief priest." The office was one of high dignity, and gave opportunities for gaining possession of the throne.
Smith's Bible Dictionary [2]
Rab-mag. Jeremiah 39:3; Jeremiah 39:13. A title borne by Nergal-sharezer, probably identical with the king called by the Greeks Neriglissar. [Nergal-Sharezer], (it probably means Chief Of The Magi ; at all events, it was "an office of great power and dignity at the Babylonian court, and probably gave its possessor, special facilities for gaining the throne.").
Morrish Bible Dictionary [3]
This is not a proper name, but the title of Nergal-sharezer. Jeremiah 39:3,13 . It has been supposed by some to signify 'chief of the Magi,' and by others, 'chief priest.' On the monuments it is given as ruba emga, which has been interpreted 'the glorious prince.' This would be an appropriate title if Nergal-sharezer is the same person who became Neriglissar the king.
Hawker's Poor Man's Concordance And Dictionary [4]
A general in the king of Babylon's army. ( Jeremiah 39:3) The word is compounded of Rab and Magi—the chief of the magi, or wise men.
