The scriptural texts for tefillin are obscure in literal meaning. For example, the verse in Deut. 11:18 does not designate what specifically to bind upon your arm, and the definition of totafot is not obvious. It is the Talmud, the authoritative oral tradition for Rabbinic Judaism, which explains what are to be bound to the body and the form of tefillin.
