The Jewish ritual of affixing a Mezuzah
What is a Mezuzah?
Mezuzah is a Hebrew word meaning doorpost. However it has evolved to refer to the case that holds the piece of parchment that is hung on the doorposts of Jewish houses.
What is inscribed on the parchment inside the Mezuzah?
Two sections from the book of Deuteronomy are written on the parchment. These sections are part of the Jewish prayer, the Shema. Within this prayer mention is made of belief in G-d's Oneness. Seven hundred and thirteen letters are written on the parchment. If even one letter is missing or incorrectly written, the parchment is invalid. A Hebrew acronym, Sha-dai, a shortened version of Shomer Daltot Yisrael, is written on the reverse side of the parchment. This acronym is one of G-d's names and means Guardian of the Doorways of Israel. The scroll is rolled from left to right before being placed in the case so that Sha-dai is visible.
The Mezuzah Case
The parchment is placed in a case for protection. If a case is unavailable, the scroll can be wrapped in thick paper or similar material. If a case is bought with a scroll already enclosed, be sure to buy from a reliable source. A case can be made from a variety of materials. Remember that what's inside the case is more important than the case itself.
What is the source for affixing the Mezuzah?
"And you shall write them [referring to the words of Shema] on the doorposts of your house and on your gates." -Deuteronomy 6:9; 11:20
Which doorposts require a Mezuzah?
Every single room in a house or building requires a Mezuzah. That is, every room larger than 6.5 feet by 6.5 feet with a full doorway. It should be noted that a room of lesser proportions may have a Mezuzah on the doorpost; it just won't require a blessing upon affixing. Rooms that don't need a Mezuzah include bathrooms, shower rooms and the like.
