In Jewish homes worldwide, Mezuzahs* stand guard, ensuring G-d’s protection of the home and its residents. Jewish law stipulates that the Mezuzahs be written by a certified scribe and checked approximately every three and a half years to ensure that none of the letters in the scroll have been damaged by weather conditions, fading, or any other circumstances. If the scroll is damaged, it is rendered “unkosher” and can no longer serve to protect the home.
