When a Jewish family or someone on his own, moves into a new house is describe as a (mini) sanctuary, and the table from which food is eaten has been called a miniture altar. For a Jewish home is to be  not just a place to live, but also a place we live accordding to our traditions and values.

The Chanukas Habayis, the dedication of the home, which is a ceremony and marks the family entering the home and blessed the home to its sacred prupose.

The ritual of the Chanukas Habayis ceremony is putting up the Mezuzah on the doorposts of the house.

                           🔹️ Mezuzah🔹️

The Mezuzah is a Kosher klaf on which is handwritten in Kosher inkt the Shema by a sofer, and aflix on the righthand side of the doorposts, ouside of the house and on every doorpost inside our home except for the bathroom.

The mezuzah is a mitzvah, a covenant between the Jewish people and HaShem. Righteous gentiles are not under obligation to keep the mitzvos, but they can take on the 7 Noahide Laws.

A klaf must to be examined once every three and a half years or twice every seven years by a sofer, the outdoor mezuzah should be checked more often. The mezuzah shows that it is a Jewish home and protect the family in and outside the house.

The meaning of a mezuzah is the Klaf, and when we call the doorpost a mezuzah, which not holding the door in place, but enabling a mitzvah. So if it isn't for the Klaf there would be no reason, as it would be just like empty doorpost.

The Mezuzah, a divine mitzvah in which the Torah states it reward,

 " And these words, to love the lord your G'D, which I command you this day shall be in your heart.You shall teach them dilligently to your children, speaking of them at home and away, morning and night. And you shall bind them as a sign upon your hand and between your eyes. And you shall write them on your doorposts of your house and on you gates." ~Devarim 6:6-9
