Tefillin (תְּפִלִּין) are a pair of black leather boxes containing Hebrew parchment scrolls. A set includes two—one for the head and one for the arm. Each consists of three main components: the scrolls, the box and the strap.
he Torah commands Jewish men to bind tefillin onto their head and upper arm every weekday, in fulfillment of the verse (Deut. 6:8), “You shall bind them as a sign upon your hand, and they shall be for a reminder between your eyes.” (More on what this means below.)
Tefillin is an incredibly powerful mitzvah. The experience of putting on tefillin has changed many people’s lives.
