The Mezuzah is a small case in which a small hand written scroll of parchment (called a klaf) is placed. The meaning of the Hebrew word Mezuzah is simply "a doorpost". According to the Talmud, keeping the commandment of mezuzah brings long life and protection for members of the home. Furthermore, it is believed every mezuzah that is affixed adds to the divine protection of people everywhere. The name of God (letters Shin-Daled-Yud) is written on the back of mezuzot. It is said that these letters also stand for Shomer Daltot Yisrael, which means Guardian of the Doors of Israel. The scroll contains the words of the "Shema Israel" (Deuteronomy 6:4-9) passage, in which God commands Jews to keep His words constantly in their minds and in their hearts. The meaning of the words "Shema Israel" is "Hear Israel". The scroll also contains another passage (Deuteronomy 11:13). The passages are written in Hebrew, and contain 22 lines of 713 painstakingly written letters. On the back of the scroll, the name of God is written. The scroll is then rolled so that the first letter of the Name (the letter Shin) is visible (or, more commonly, the letter Shin is written on the upper exterior of the case, as we can see in this Lladr representation). The scroll is not included in the Lladr piece.
It's made in white porcelain in matte finish. Decorated with blue enamels, the letter Shin is painted in golden luster.
