The Jewish Mezuzah has a very important role in protecting us from bad things that
might happened to us.
It is important to check the mezuzah every few years, in order to see that the klaf is still kosher by checking that the
letters inside the parchment are not invalidated.
Mezuzahs are mandatory in every jewish home, businesses and offices.
The mezuzah should be put in the entrance to the house and in every room in the house.
The Mezuzah ” klaf” is made of parchment, written by a scribe – sofer stam, and contains two parashot from the
the first parasha: “Shema Yisrael ” .
The second parasha: “Vehayah”.
Before attaching the mezuzah a blessing should be say, the blessing is:
Barukh atah Adonai Eloheinu melekh haolam asher kideshanu bemitzvotav vetzivanu liqvoa’ mezuzah.
The english translation for this blessing is:
Blessed are You Lord our God the King of the Universe, Who sanctified us with His mitzvot,
and commanded us to affix a mezuzah.
