Tefillin, also known as phylacteries, are sets of small black leather boxes.

They contain parchment scrolls inscribed with specific verses from the Torah. These items serve as a physical sign and a remembrance of the Exodus from Egypt. In Jewish tradition, they are worn during the morning prayer service known as Shacharit. While many Orthodox and traditional Conservative communities limit their use to men, some Reform and Conservative communities allow Jewish adults of any gender to wear them.

The mechanism for wearing tefillin involves two distinct components: the arm tefillah and the head tefillah. The arm tefillah is placed on the upper, non-dominant arm.

A long black leather strap, or retsu'ot, is used to secure the box. This strap is wrapped around the forearm, the hand, and finally the middle finger. The head tefillah is positioned on the forehead between the eyes.

The straps are tied in specific ways to form Hebrew letters. The knot for the head tefillah forms the letter dalet. The knot for the arm tefillah forms the letter yud. Together with the letter shin molded on the box, these spell Shaddai, a name for God.

There are different types of tefillin based on how the leather boxes are manufactured. Some are called peshutim, which are simple boxes made from several pieces of parchment. Higher quality versions include dakkot, which are thin, and gassot, which are thick and durable.

The boxes are ideally fashioned from a single piece of animal hide. The head tefillah features a cubical section called the ketzitzah. Below this is a wider base known as the titura. A passageway called the ma'avarta allows the strap to be threaded through the base.

History shows that the practice of wearing tefillin is very ancient. Archaeological finds at Qumran suggest that Jews understood the biblical commandment to be literal.

The word tefillin is the plural of tefillah. Some scholars, such as Jeffrey H. Tigay, suggest the word originally meant "headband." This may relate to ornamental bands worn by Levantine populations in the Hebrew Biblical period. While some historical accounts suggest men wore them all day, most people today remove them after morning services.

The significance of tefillin is deeply tied to spiritual discipline and devotion. The 14th-century Sefer ha-Chinuch states they help a person manage worldly desires.

The 16th-century scholar Joseph Caro explained that placement is symbolic. The arm tefillah is placed near the heart, and the head tefillah is placed near the brain. This demonstrates that both the heart and the mind are dedicated to God. Many people also practice hiddur mitzvah, which means beautifying a commandment. They may use high-quality leather or beautiful bags to show glory to the Creator.

Manufacturing these items requires extreme precision and skill.

A scribe must write four specific biblical passages on parchment scrolls called klaf. The arm tefillah contains one large compartment for a single strip of parchment. The head tefillah contains four separate compartments for four individual scrolls. The scribe must use a specific Hebrew script known as Ashuri. There are different styles, such as Beis Yosef, Arizal, and Velish. Any error in the writing or the ink can invalidate the tefillin.

Beyond personal prayer, tefillin have been viewed through various lenses in scholarship. Some non-Orthodox scholars have suggested they may have served an apotropaic function. An apotropaic object is one intended to turn away evil or bad luck.

Early Rabbinic sources mention tefillin in relation to repelling demons. However, the Talmud specifically differentiates tefillin from common amulets. They remain a central part of Jewish identity and religious practice, connecting the wearer to ancient laws and the history of the Exodus.
