The Origins of Tefillin

The archaeological evidence, together with consideration of various biblical passages and even of halakhah, suggests that tefillin were originally practiced as a length-of-days amulet. While we cannot be sure when this began, the ritual – in a form fairly similar to the one known today – already existed during the late Second Temple period, which witnessed the Jewish encounter with Hellenistic culture. | Dr. Yehudah Cohn
