A Brief Introduction to the Mezuzah
The Torah states “…and these words that I command you today shall be upon your heart and you shall write them on the doorposts of your house and upon your gates.”
This mitzvah (commandment) is observed by placing a small box containing a passage from Deuteronomy 6:4-9, along with the words of a companion passage, Deut. 11:13-21. On the back of the scroll, a name of G-d is written.
The scroll is then rolled up and placed in the case, so that the first letter of the Hebrew name for G-d, Almighty, the letter Shin is visible.
The scroll must be handwritten by a scribe, specializing in writing Hebrew texts on parchment, must be placed in the case to fulfill the mitzvah.
The case and scroll are then affixed to the right side doorpost on an angle. A brief blessing is recited for affixing the Mezuzah.
Traditionally, when one passes through a door with a mezuzah on it, one touches the mezuzah and then kiss the fingers that touched it, as a sign of respect for G-d and the mitzvot mentioned in them.
A non-kosher scroll is included with the mezuzah.
