NERGAL-SHAREZER (nûr'găl-sha-rē'zêr, Assyr. nerghal sar-usar, may Nergal protect the prince). The son-in-law of Nebuchadnezzar. He is also called Neriglissar. Evil-Merodach (Amil-Marduk), who succeeded Nebuchadnezzar as king, was assassinated by Nergal-Sharezer, who then became king (Jer.39.3-Jer.39.13).
NERGAL-SHAREZER nûr’ găl shə rē’ zər (נֵרְגַ֣ל שַׂר־֠אֶצֶר, protect the king!). Name of a senior official with the Babylonian army at Jerusalem in 587 b.c. (Jer 39:3, 13). When a breach was made in the city’s defenses, he, with other princes, occupied the Middle Gate (Jer 39:3). With other officers he had Jeremiah taken out of prison and entrusted to Gedaliah (39:14).
He has sometimes been equated with Neriglissar who was according to Berosus a son-in-law of Nebuchadrezzar. Neriglissar (559-556) was the son of a private citizen and his campaign into Cilicia is described in a fragment of the Babylonian Chronicle.
International Standard Bible Encyclopedia (1915)
A Babylonian officer, the "Rab-mag," associated with Nebushazban in the care of Jeremiah after the fall of Jerusalem (Jer 39:3,13). According to Hommel (article "Babylon," Hastings, Dictionary of the Bible (five volumes)) and Sayce (Hastings Dictionary of the Bible, under the word), Nergal-sharezer is to be identified with Neriglissar who succeeded Evil-merodach on the throne of Babylon (compare Cheyne and Johns, Encyclopedia Biblica, under the word).
