The Area between the Ulam and the Mizbeach: The Laver: Sanctity

The laver is a service (sacred) vessel, as are the other vessels in the Mishkan. In the Mishkan, it was initially sanctified by anointing with oil. In the Mikdash, it was "dedicated through its service." From this we derive that it cannot be used for ordinary, (non-holy), purposes.
