Laws & Customs

The Mezuzah signifies the sanctity and blessing of the Jewish home. Actually, it is a portion of Holy Torah, inscribed in the same manner and script as a Torah. It is an "original" sanctified document in accord with laws and precepts that dare not be compromised.
On this sacred scroll of parchment are inscribed two passages from Torah, "Shema Yisroel" and "Vehaya" (Deuteronomy 6:4-9 and 11:13-21).
It is customary, upon entering or leaving a residence, to touch the Mezuzah. This reverence acknowledges our belief in the "Shema Yisroel," the Jewish declaration of faith, which expresses the unity of G-d, the duty of loving and serving Him with our whole being, and our obligation to observe the mitzvot in and out of the home.
Because it presents basic principles of our faith, the Mezuzah is our responsibility to visitors as well as to ourselves. When a Mezuzah is not valid, its blessings are nullified. Even if one letter or part of a letter is missing or imperfect, the Mezuzah may not be used. Only a "Kosher" Mezuzah sanctifies and protects the home, as well as fulfills the saying of the Psalmist, "G-d will guard your going and coming from now and for all time."
That is why when you purchase a Mezuzah for yourself or make it a gift to a relative or friend, you are obligated to assure its validity. Be certain that it is hand written and that you obtain it from a reliable source.

If it's written in Torah script by an ordained and dedicated scribe...
Then it identifies, sanctifies and protects your home with its blessing...

Just as a Torah is adorned with ornaments, the Mezuzah is encased in any variety of traditional or contemporary cases. The contents, however, may never be compromised.
