("doorpost"). The small scroll of parchment containing selected biblical passages which is traditionally affixed to the doorposts of the Jewish home. The custom is derived from the biblical commandment to "write them upon the doorposts of your house and in your gates" (Deut. 6:9, 11:20). The term
mezuzah, whose literal meaning in Hebrew is "doorpost," was later taken to mean the scroll of parchment itself upon which the biblical passages are written. The first passage (Deut. 6:4-9) contains the opening paragraph of the basic Jewish confession of faith, the
Shema. It includes the commandments to: 1) love God; 2) study the Torah; 3) read the
Shema prayer, expressing the unity of God, twice daily; 4) wear
Tefillin; and 5) affix a
mezuzah. The second passage (Deut. 11:13-21), which is also part of the daily
Shema reading, associates prosperity and well-being with proper observance of the commandments, and recapitulates the commandments of the first paragraph.
The mezuzah must be written by a qualified Scribe on parchment made from the skin of a clean animal. The scroll is rolled and placed into a case with a small opening through which the word Shaddai ("Almighty"), written on the back of the parchment, is visible. The mezuzah is attached to the upper part of the doorpost at the entrance of each room in a slanting position. This position is a compromise resulting from the dispute between Rashi, who favored a vertical position, and his grandson R. Jacob ben Meir (Tam), who maintained that the mezuzah should be attached horizontally.
In earlier periods, it was common to place the mezuzah parchment directly into a small compartment hollowed out of the doorpost.
A mezuzah must be placed on every right-hand doorpost which fulfills the following conditions:
(1) The room for which the doorway is an entry must be at least four by four cubits (6 by 6');
(2) The doorway must have doorposts on each side;
(3) The doorway must have a lintel;
(4) The doorway must be an entrance into a room with a ceiling (although this is disputed);
(5) The doorway must have doors that open and close (also disputed);
(6) The doorway must be a minimum of 40 inches high and 16 inches wide;
(7) The room must be for ordinary dwelling;
(8) The room must be for human, not animal, dwelling;
(9) The room must be for dignified dwelling or use (thus toilets and bathrooms are exempt);
(10) The room must be for continuous or permanent dwelling (thus a tent and a Sukkah are exempt).
Although synagogues and public dwellings are exempt from the commandment, as they are not ordinary dwellings, it has become customary to attach mezuzot to their entrances.
When the mezuzah is affixed, the benediction "Who has commanded us to affix the mezuzah" is recited. In the Diaspora, affixing the mezuzah may be deferred for 30 days after entering a rented dwelling, while in the Land of Israel the custom is to attach it immediately. Mezuzot should be checked twice every seven years by a qualified expert to make certain they are still valid.
It became customary among traditional Jews to touch the mezuzah with their hand upon leaving or entering the house to express awareness of the fulfillment of the commandment, and to show reliance upon God's protection.
