What is "shebuel"

Shebuel was the son of Gershom, and a grandson of Moses and Zipporah. He, along with his first-cousin Rehabiah (the first-born and only son of Eliezer), were described as chiefs and included in the Tribe of Levi. Shebuel is also described as "ruler of the treasures". His name means "captive of God" or "returned of God". His patrilineal lineage can be traced back to Abraham, Isaac, and Jacob since Levi is both his great-great grandfather (through Jochebed) and great-great-great grandfather (through Amram). He is also descended from Jethro and Jethro's ancestor Midian, son of Abraham and his second wife Keturah, through his paternal grandmother Zipporah.
