What’s That On Your Door?

Ever notice a strange-looking oblong box affixed to the doorpost of a home or building in your neighborhood? Ever wonder what it was? Chabad.orgoffers a great explanation!


No, it’s not a Jewish doorbell. It’s a home security device called a mezuzah, and it’s wired into the Ultimate Protection Agency. The software inside this gadget is a scroll with the words beginning, “Hear O Israel, the Lord is our God; the Lord is one.” Those powerful words sum up the mandate of a Jew: to infuse the world with G‑d’s oneness. We place the mezuzah on our doorposts, and G‑d’s oneness surrounds us and protects us.

You’ll need:

  1. A mezuzah scroll. The mezuzah must be hand-written by a scribe, on specially prepared parchment, with specific types of quill and ink. The market is filled with printed or improperly prepared mezuzahs, so make sure to purchase yours from a reliable source.
  2. We place them on our doorposts, and God’s oneness surrounds us and protects us.
  3. Hammer and nails, strong glue or double-sided tape.


On every doorway in your home or office leading into a proper room—a space at least 6.5 × 6.5 feet—except for the bathroom. This includes hallways, walk-in closets, etc. On the right doorpost—going with the direction towards which the door opens.


Recite: Blessed are you, Lord our God, King of the universe, who has sanctified us with His commandments and commanded us to affix a mezuzah. Touch the mezuzah as you enter and leave, and then kiss the fingers that touched it.
