Another clue may come from the meaning of the name Zerubbabel: The name Zerubbabel consists of two parts. The second part of this name is obviously the same as the Hebrew word for Babel / Babylon. The origin of the first part is a bit of a mystery.
Insubordination is generally a punishable offense in hierarchical organizations which depend on people lower in the chain of command doing what they are expected to do.
The elements of insubordination commonly include: (1) a direct or implied order that was issued to an employee, (2) the employee received and understood the order and (3) the employee refused to obey the order either through a statement of refusal or nonperformance. Insubordination should not be confused with insolence.
