'Governor' in the Bible

and his son Beerah, whom King Tiglath-pileser of Assyria carried away into exile, and who was a governor of the descendants of Reuben.

And did eat and drink before the LORD on that day with great gladness. And they made Solomon the son of David king the second time, and anointed him unto the LORD to be the chief governor, and Zadok to be priest.
