If you watch Orthodox Jews pray at the Wailing Wall of Jerusalem, you might wonder about the leather band wrapped around their forearms and the box strapped to their heads. The objects are called the tefillin, worn during a prayer ritual that some believe dates back to the time of Moses (Deuteronomy 6:6-8). The process to don the tefillin is very elaborate and must be performed in an exacting manner. This illustrates that in Jesus’ time, Jewish prayer was very focused on the “how”—praying in a specific way.
