How to Affix the Mezuzah: Practical Guide

How to Affix the Mezuzah: Practical Guide

The mezuzah is a parchment scroll (klaf) hand-written by a sofer (scribe) containing the paragraphs of the Shema Israel (Deuteronomy 6:4-9 and 11:13-21). It is affixed to the doorposts of Jewish homes as fulfillment of the commandment "you shall write them on the doorposts of your house" (Deuteronomy 6:9).

Purchasing a Kosher Mezuzah

The klaf must be parchment made from the skin of a kosher animal, prepared specifically for this purpose. The text must be handwritten by a trained sofer with special black ink in square Hebrew script. Printed or photocopied mezuzot are not acceptable. Purchase mezuzot from reliable sources that guarantee their kashrut.

Which Doorways Require a Mezuzah?

Every doorway that has two doorposts, a lintel, and a door that opens, in a living space at least 4×4 cubits (approximately 2×2 m), requires a mezuzah. This includes:

• Exterior doors of the house
• Bedrooms, kitchen, living room
• Offices and studies
• Not required: bathrooms (not dignified spaces), very small closets, garages

The Blessing When Affixing

Before affixing the mezuzah, recite:

Baruch atah Adonai, Eloheinu Melech ha'olam, asher kid'shanu b'mitzvotav v'tzivanu likboa mezuzah.

("Blessed are You, Lord our God, King of the universe, who sanctified us with His commandments and commanded us to affix the mezuzah.")

Position: Vertical or Angled?

• Ashkenazi custom: Placed at a slant, with the top leaning inward. This custom arose as a compromise between Rashi (vertical) and Rabbeinu Tam (horizontal).
• Sephardic custom: Placed vertically.
• The mezuzah is placed on the lower part of the upper third of the doorpost, on the right side when entering.

Maintenance and Inspection

Mezuzot should be inspected by a sofer at least twice every seven years, or after events that may damage them (moves, humidity, accidents). If the mezuzah is damaged or the parchment has deteriorated, it must be replaced.

Customs When Passing

It is customary to kiss one's fingers and touch the mezuzah upon entering and leaving, as an expression of love for the commandments and divine protection.

The mezuzah is not a magic amulet, but a constant reminder of God's presence in the home.
