What Is a Mezuzah and Why Do We Have One?
A mezuzah is a handwritten parchment scroll containing the first two paragraphs of the Shema. It is placed on the doorposts of a Jewish home as a fulfillment of the Torah commandment, “And you shall write them upon the doorposts of your house and upon your gates” (Devarim 6:9 and 11:20).
Quick Facts
What it is: A handwritten parchment scroll containing the first two paragraphs of the Shema.
Who writes it: A qualified sofer, by hand, according to the laws of mezuzah.
Where it goes: On the right side of the doorway when entering, near the bottom of the upper third of the doorpost.
How often it is checked: Twice every seven years, and sooner if it is exposed to moisture or harsh weather.
The mezuzah itself is the parchment inside the case, not the decorative case surrounding it. The words must be handwritten by a qualified sofer (Jewish scribe) according to detailed halachic requirements. A printed scroll does not fulfill the mitzvah.
A mezuzah serves as a constant reminder of our connection to Hashem and of the Jewish values that should fill our homes. The mezuzah is also associated with Hashem’s protection over the home and those who live inside it.
Generally, a mezuzah is required on the doorways of rooms used for normal living purposes. Bathrooms are exempt, and there are additional rules regarding closets, very small rooms, unusual doorways, balconies, garages, and other areas. Because determining which doorways require a mezuzah can sometimes be complicated, a rabbi should be consulted when there is any doubt.
Proper mezuzah placement follows a few basic rules. A mezuzah is normally placed on the right side of the doorway when entering, near the bottom of the upper third of the doorpost. Determining which side is considered the entrance can become more complicated with interior rooms and certain doorway configurations. Ashkenazim generally place the mezuzah at an angle, while Sephardim place it vertically.
When affixing a mezuzah to a doorway that requires one with a blessing, the following mezuzah blessing is recited before putting it up:
“Baruch Atah Ado-nai, Elo-heinu Melech HaOlam, Asher Kidshanu B’Mitzvosav V’Tzivanu Likboa Mezuzah.”
(“Blessed are You, Hashem, our G-d, King of the universe, Who has sanctified us with His commandments and commanded us to affix a mezuzah.”)
Not every doorway requires a blessing. In cases of doubt, a rabbi should be consulted, following the halachic principle of Safek Berachos Lehakel (when there is uncertainty about whether a blessing is required, we refrain from reciting it).
Having a mezuzah on the door is not enough. The parchment must remain kosher. Over time, moisture, heat, age, or damage can cause letters to crack, fade, or become invalid. How often to check depends on the conditions, but mezuzos in a private home should be checked by a qualified sofer twice every seven years. Mezuzos exposed to harsh weather or moisture may require more frequent inspection. Here in South Florida, the humidity makes regular mezuzah checking especially important, since moisture is the most common cause of cracked and faded letters.
If you are unsure whether a doorway requires a mezuzah, whether your mezuzah is positioned correctly, or when your mezuzos were last checked, consult your rabbi or contact Kosher Your Kitchen for mezuzah checking and installation across Miami and South Florida.
Frequently Asked Questions
How often should mezuzos be checked?
Mezuzos in a private home should be checked by a qualified sofer twice every seven years. Mezuzos that face moisture or harsh weather should be checked sooner. In South Florida, humidity is the most common cause of cracked and faded letters, so regular checking matters even more.
Does a bathroom need a mezuzah?
No. Bathrooms are exempt from mezuzah. The doorways that require one are those of rooms used for normal living purposes.
Which doorways in a house need a mezuzah?
Generally, the doorways of rooms used for normal living purposes require a mezuzah. There are additional rules for closets, very small rooms, balconies, garages, and unusual doorways. When there is any doubt about a doorway, consult a rabbi.
What is written inside a mezuzah?
The first two paragraphs of the Shema are written on the parchment. They contain the verses “And you shall write them upon the doorposts of your house and upon your gates” (Devarim 6:9 and 11:20).
Is a printed mezuzah kosher?
No. A mezuzah must be handwritten by a qualified sofer according to detailed halachic requirements. A printed scroll does not fulfill the mitzvah, no matter how nice the case around it looks.
Can I hang a mezuzah myself?
Yes. A homeowner can affix a mezuzah and recite the blessing. What matters most is correct placement and a kosher scroll. If you are unsure about placement, or about whether a doorway requires one, contact Kosher Your Kitchen for guidance anywhere in the Miami and South Florida area.
