Have you ever noticed that Jewish homes have a little box attached to the doorpost? It’s a slanted box on the outside of the home (and sometimes on doorposts of interior rooms). This little box is called a mezuzah, and it’s one of the amulets that Jews have used throughout history to bring protection to themselves. (I have also written about another Jewish amulet- demon bowls.)
A mezuzah is a small box affixed to the doorpost of the home. It contains a scroll with text from the Torah, specifically Deuteronomy 6:4-9 and 11:13-21:
Hear, O Israel, the L‑rd is our G‑d, the L‑rd is One.
You shall love the L‑rd your G‑d with all your heart, with all your soul, and with all your might. And these words which I command you today shall be upon your heart. You shall teach them thoroughly to your children, and you shall speak of them when you sit in your house and when you walk on the road, when you lie down and when you rise. You shall bind them as a sign upon your hand, and they shall be for a reminder between your eyes. And you shall write them upon the doorposts of your house and upon your gates.
And it will be, if you will diligently obey My commandments which I enjoin upon you this day, to love the L‑rd Your G‑d and to serve Him with all your heart and with all your soul, I will give rain for your land at the proper time, the early rain and the late rain, and you will gather in your grain, your wine and your oil. And I will give grass in your fields for your cattle, and you will eat and be sated. Take care lest your heart be lured away, and you turn astray and worship alien gods and bow down to them. For then the L‑rd’s wrath will flare up against you, and He will close the heavens so that there will be no rain and the earth will not yield its produce, and you will swiftly perish from the good land which the L‑rd gives you. Therefore, place these words of Mine upon your heart and upon your soul, and bind them for a sign on your hand, and they shall be a reminder between your eyes. You shall teach them to your children, to speak of them when you sit in your house and when you walk on the road, when you lie down and when you rise. And you shall inscribe them on the doorposts of your house and on your gates-so that your days and the days of your children may be prolonged on the land which the L‑rd swore to your fathers to give to them for as long as the heavens are above the earth.
The outside of the mezuzah is usually affixed with the Hebrew letter shin which stands for Shaddai- one of the names of G-d. The name Shaddai is often on the reverse of the scroll. Sometimes, other names and charms were written on the scroll as well- names of angels, kabbalistic imagery, etc.
Historically speaking, the mezuzah was used as an amulet and talisman, both warding off evil and attracting blessings to those within the home. As you can see from the text, having the scroll affixed to the doorpost was seen as a method for ensuring prosperity, fertility, and long life. Traditionally, the belief was that the scroll had to be deemed kosher for the the mezuzah to be effective. At various times, when negative things would happen, it would be blamed on the person not having a mezuzah on their doorpost, or that the mezuzah was ineffective due to its non-kosher status. Many times, a person was urged to have their mezuzah checked to ensure it remained kosher after negative things happened.
Many people claim that the mezuzah is not an amulet or talisman, but is simply an object used to fulfill a divine commandment. But, it can’t be argued that at times throughout history the object has been seen as having magical or mystical properties. The same goes for today- some do still view the mezuzah as an amulet. Whether or not a Jew believes the object has magical properties, the object is often placed, just as prescribed, kosher and on the doorpost. If the reason is to follow a divine commandment, I question why it is important to obey that command. Surely, a person gets something out of following an instruction- even if it is just feeling good about oneself. No matter how you look at it, the mezuzah does serve as an amulet in some way.
