According to their interpretation of Deuteronomy 6: 8, 9, the rabbis held that Jewish men had to pray wearing tefillin, or phylacteries, and that a mezuzah was to be placed on each doorpost.
Rabiinid arvasid vastavalt oma tõlgendusele 5. Moosese 6: 8, 9 kohta, et juudi mehed peavad palvetades kandma palverihmasid, ja et igale ukse piitjalale tuleb kinnitada mezuzah.
