What is "simbar-shipak"

Simbar-Šipak, or perhaps Simbar-Šiḫu, typically inscribed sim-bar-ši-i-ḪU or si-im-bar-ši-ḪU in cuneiform, where the reading of the last symbol is uncertain, “offspring of (the Kassite moon god) Šipak”, ca.1025-1008 BC, founded the 2nd Dynasty of the Sealand, Babylon’s 5th Dynasty and conducted a program of restoration of a number of temples that had been destroyed earlier by the marauding Arameans and the Sutû. His identification with the Sibir (Si-bir) named by Ashurnasirpal II in his annals as having earlier captured and laid waste Atlila (probably modern Bakrawa), a city on Assyria’s eastern flank, remains unresolved.
