mezuzza, oggetto rituale ebraico che consiste in una scatolina contenente un rotolino di pergamena con sopra scritta la preghiera fondamentale ebraica dello Shemà e che viene inchiodata sulla porta dell'abitazione di ogni ebreo
A mezuzah ( "doorpost"; plural: מְזוּזוֹת mezuzot) is a piece of parchment (often contained in a decorative case) inscribed with specified Hebrew verses from the Torah ( and ). These verses compose the Jewish prayer "Shema Yisrael", beginning with the phrase: "Hear, O Israel, the LORD (is) our God, the LORD is One". In mainstream, i.e. Rabbinic Judaism, a mezuzah is affixed to the doorframe of Jewish homes to fulfill the mitzvah (Biblical commandment) to inscribe the words of the Shema "on the doorposts of your house" . Some interpret Jewish law to require a mezuzah on every doorway in the home apart from bathrooms and closets too small to qualify as rooms. The parchment is prepared by a qualified scribe (a "sofer stam") who has undergone many years of meticulous training, and the verses are written in black indelible ink with a special quill pen. The parchment is then rolled up and placed inside the case.

English to English translation of Mezuzah
A small box, usually decorated, affixed to the doorpost of a Jewish home. It marks the distinction between the profane outside world and the holy world inside. The box contains a piece of paper with the words of the Shema in Hebrew written on it. Observant Jews will touch the mezuzah and say a blessing as they go in and out of the house.
