What is "rabsaris"

Rabsaris , possibly means "Chief of officers," is the name or title of two individuals mentioned in the Bible.

• Rabasaris (in the D-R and the Vulgate; ) — One of the three officers whom the King of Assyria ( Sennacherib) sent from Lachish with a threatening message to Jerusalem (2 Kings 18:17).
• Rabsares (in the D-R and the Vulgate) A prince of Nebuchadnezzar (Jeremiah 39:3,13). While originally translated to be the name of the persons it referred to, Rabsaris is now thought to be the name of an office or rank, not an individual.
