What are "Tefillin" in the context of Halacha?

Tefillin, in the context of Halacha, refers to phylacteries that are worn during weekday prayers, specifically during the morning service. These are two small leather boxes containing scrolls of parchment inscribed with verses from the Torah, including passages that emphasize the importance of God's commandments. The act of wearing tefillin serves as a physical reminder of one's duties to God and the commitment to observe the commandments.

This practice is rooted in Torah commandments and holds significant symbolic meaning, representing the connection between one's heart, mind, and actions. The tefillin are worn on the arm, facing the heart, and on the forehead, symbolizing the integration of spiritual thoughts and intentions with physical actions.

The other options describe various Jewish practices, but they do not accurately capture the essence of tefillin. Special garments worn on holy days pertain to clothing like the tallit or kittel, prayer scrolls generally refer to a Sefer Torah, and ceremonial food might relate to holiday meals or specific rituals but does not encompass the concept of tefillin.
