He not only recognized his royal rank, but gave him precedence over all the captive kings resident at Babylon.

Josephus says that he even admitted Jehoiachin into the number of his most intimate friends.

Perhaps he may have designed him some further advancement, and may in other respects have entertained projects which seemed strange and alarming to his subjects.

At any rate he had been but two years upon the throne when a conspiracy was formed against him; he was accused of lawlessness and intemperance; his own brother-in-law, Neriglissar, the husband of a daughter of Nebuchadnezzar, headed the malcontents; and Evil-Merodach lost his life with his crown.
Neriglissar, the successful conspirator, was at once acknowledged king.

He is probably identical with the "Nergal-shar-ezer, Rab-Mag," of Jeremiah, who occupied a prominent position among the Babylonian nobles left to press the siege of Jerusalem when Nebuchadnezzar retired to Riblah.
