Rabmag

Rabmag was a title, not a personal name, borne by Nergal-sharezer, one of the Babylonian princes who sat at the gate after the fall of Jerusalem in 586 BC (Jeremiah 39:3, 13). The title's meaning is debated: it may derive from the Akkadian rab mugi or a similar official title denoting a high military or court rank. Nergal-sharezer the Rabmag later became king of Babylon (Neriglissar, 560–556 BC), having killed Evil-merodach. He and the other officials were commanded to treat the prophet Jeremiah kindly and to take care of him after the city's fall.
