Mark will explain the meaning of this ritual and its Scriptural source. Tefillin (also known as phylacteries) are worn by men in traditional synagogues for the morning worship except on Shabbat and Jewish holy days. The tefillin are leather straps holding small leather boxes in which are slips of parchment with passages from the Torah written on them. One box is worn on an arm, and the other on the forehead.
