Abstract: A mezuzah having a base portion which is permanently mountable to a doorway fixture, and having a housing portion with a bore in one of its ends for receiving a scroll bearing Biblical text therein, with the housing member being slidably engageable with the doorway mounted elongated base member. The lower, bore communicating end of the housing member abuts a sealing member of the base member upon engagement of the housing member to the base member to effectively seal the bore in which the scroll is disposed to prevent the scroll from falling out and to shelter the scroll. The scroll may be periodically checked for integrity or replaced by sliding the housing member off of the base member to gain easy access to the bore, with the housing member then slidable back onto the base member to secure the scroll in the housing member. A latch may be provided to selectively prevent slidable disengagement of the housing member from the base member.
