What Is Tefillin?

Understanding the Meaning and Importance of Tefillin in Jewish Tradition

Tefillin are sacred black leather boxes containing handwritten Torah passages that are traditionally worn by Jewish men during weekday morning prayers. Also known as phylacteries, tefillin serve as a physical reminder of one’s connection to God and commitment to observing the commandments of the Torah.

Each set of tefillin includes two boxes—one worn on the arm and one on the head—secured with leather straps according to Jewish law. Inside each box are carefully handwritten Torah passages prepared by a certified Sofer STaM on kosher parchment.

For centuries, tefillin have been an essential part of Jewish prayer and spiritual life, symbolizing faith, devotion, and remembrance of God’s commandments.

What Is Written Inside Tefillin?

Inside every pair of kosher tefillin are four passages from the Torah that emphasize the unity of God and the importance of remembering His commandments.

These handwritten passages are written by a qualified Sofer STaM using traditional methods and include verses from:

  • Exodus
  • Deuteronomy

Every Hebrew letter must be perfectly formed according to halachic standards. Because these parchments are handwritten, they require careful handling and periodic inspection to ensure they remain kosher.
