What Is Written in a Mezuzah? A Look Inside the Scroll
Almost every Jewish home has a mezuzah on the doorpost, but few have ever opened the case and read what is written on the scroll inside. The mezuzah is not an amulet and not a decoration: it is a precise text from the Torah, handwritten on parchment according to ancient, binding rules of writing. This article goes through the content itself, line by line, and explains what is written on the back of the scroll and how it is written.
Two passages from the Torah
The mezuzah scroll contains two portions from the Book of Deuteronomy. The first is the "Shma Yisrael" portion (Deuteronomy 6:4-9), which opens with the familiar words "Hear, O Israel: the Lord our God, the Lord is one' and continues with the commandment 'And you shall love the Lord your God." The second portion is "And it shall come to pass, if you will hearken' (Deuteronomy 11:13-21), which deals with the acceptance of the yoke of the commandments and the reward for following the path of the Torah. Both portions conclude with the exact same commandment: "And you shall write them upon the doorposts of your house and upon your gates." In other words, the text of the mezuzah contains within it the source for the obligation of the mezuzah itself, a complete circle of a commandment testifying to itself.
Why these two passages
The two portions are the core of the Jewish faith: the oneness of God, the love of God, and the acceptance of the commandments. The Sages determined that these are the ones to be written on the doorway, so that every entry and exit from the home passes through a reminder of the home's identity and values. The mezuzah transforms the door from a mere passage into a small moment of intention, hence the widespread custom to kiss the mezuzah upon entering and leaving.
What is written on the back of the scroll
On the back of the parchment, on the outside, the scribe writes the name "Shaddai." Our Sages of blessed memory also interpreted this name as an acronym: "Guardian of the doorways of Israel." When the parchment is rolled properly, from end to beginning, the name Shaddai remains visible on the outside, and therefore on many mezuzah cases the letter Shin appears on the front, corresponding to the name behind it. On some parchments, additional letters also appear on the back, written according to an ancient tradition—a combination directed against the Name of God by the next letter in the alphabetical order.
How the scroll is written: ink, quill and parchment
What is written in the mezuzah must be written in a specific way in order to be kosher. The writing is done by hand, by an authorized *sofer stam* (scribe), on parchment made from the skin of a kosher animal prepared specifically for the commandment. The ink is black and durable, the writing is done with a quill, and every single letter must be complete and surrounded by parchment on all sides. The order of writing is mandatory: it is forbidden to complete a letter that was omitted out of sequence. Exactly twenty-two lines, in Ashkenazic or Sephardic script according to the community's tradition. A flaw in even a single letter is enough to invalidate the entire parchment, which is why a genuine parchment undergoes rigorous proofreading.
The difference between a kosher scroll and a mehudar scroll
The content is identical in every scroll, but the level of the writing differs. A kosher lechatchila scroll meets every halachic requirement; a mehudar scroll is written with greater care for the shape of the letters, uniformity and beauty, and passes stricter control. Available at Tshura is a kosher mezuzah scroll handwritten by a sofer in both grades and both scripts, with computerized proofreading and an additional review by a certified examiner, with the approval and recommendation of leading Torah authorities, from ₪180. One point deserves emphasis: a printed scroll is not a mezuzah, even if it looks identical. Only handwriting fulfills the mitzvah.
And what wraps the text: the mezuzah case
The scroll is the mezuzah, but it needs protection from sun, humidity and the wear of time, hence the mezuzah case. The case also gives the text a face toward the home: material, color and character. Anyone looking for a case that honors the scroll inside will find in the Tshura mezuzahs category carefully chosen natural stone cases, and in the guide to affixing a mezuzah , the blessing and the right way to do it.
What is not written in a mezuzah: correcting common mistakes
There are several common beliefs about the mezuzah that are worth clarifying. The mezuzah does not contain the names of the household members, nor personal requests or special blessings: the text is identical in every kosher mezuzah in the world, from Jerusalem to New York, and its power lies precisely in this uniformity. Nor is the mezuzah an amulet meant to "protect" in and of itself: the Sages emphasized that protection comes from fulfilling the commandment and from its content—the acceptance of the yoke of Heaven—not from the physical object. And finally, the Ten Commandments are not part of the mezuzah, contrary to popular belief: only the two specific Torah portions are included, in which the commandment of the mezuzah itself appears. These clarifications only enhance its value: the small parchment carries the most distilled essence of faith.
Protecting what is written
The writing on the scroll is sensitive to its surroundings, so protecting it is part of the mitzvah. Three rules: a closed, sealed mezuzah case, especially on outdoor doorways exposed to rain and sun; gentle handling of the scroll itself, ideally touching only the margins and not the letters; and a periodic check at a sofer, twice every seven years by the accepted custom, to confirm the letters are whole. A scroll kept this way lasts for decades, and the writing stays as sharp and clear as on the day it was written.
And for the curious, a few more beautiful numbers behind the text. According to the accepted tradition, the mezuzah scroll contains 713 letters in twenty-two lines, and every one of them must be complete for the whole scroll to be kosher. The opening word is Shema and the closing word is ha'aretz, the land: from the great call of faith to the promised land, in one small scroll. Some add that the mezuzah is named after its place, the doorpost, a rare case where a sacred object is called by its architectural location. These numbers and names are not mere trivia: they show how precise this text is, written in exactly the same way in every Jewish home in the world, generation after generation, hand after hand. And when a child asks what is written there, it is a lovely opportunity to open the Chumash together, read the two passages familiar from the Shema, and show that they are the very ones written at the door.
In short
A mezuzah carries two passages: Shema Yisrael and Vehaya Im Shamoa, with the name Shaddai, Guardian of the Doors of Israel, on the back of the scroll. Everything is written by hand, on real parchment, in exact letters, each one checked. Anyone who knows what is written inside looks differently at the case outside: the mezuzah is the most important text in the home, on the most fitting wall of the home.
Frequently asked questions
Which passages are written on the mezuzah scroll?
Two passages from Deuteronomy: Shema Yisrael and Vehaya Im Shamoa. Both end with the command 'and you shall write them on the doorposts of your house and on your gates', which is the source of the mezuzah obligation itself.
What is written on the back of the scroll?
On the back of the scroll the sofer writes the name Shaddai, read also as an acronym for Shomer Daltot Yisrael, Guardian of the Doors of Israel. When the scroll is rolled properly the name stays visible on the outside, which is why many cases carry the letter Shin.
Does a mezuzah contain the names of the household or personal requests?
No. The text is identical in every kosher mezuzah in the world, with no names, requests or personal blessings. The Ten Commandments are not part of the mezuzah either, contrary to a common belief.
