A mezuzah (Hebrew: מְזוּזָה "doorpost"; plural: מְזוּזוֹת‎ mezuzot) is a piece of parchment inscribed with specific Hebrew verses from the Torah, which Jewish followers of Rabbinical Judaism fix to the doorposts of their homes.^[1] These verses are the Biblical passages in which the use of a mezuzah is commanded (Deuteronomy 6:4–9 and 11:13–21); they also form part of the Shema prayer.

In mainstream Rabbinic Judaism, a mezuzah must generally be placed in every doorway in the home,^[2] with some exceptions such as bathrooms (which are not a living space) and small closets.^[3]

The klaf is prepared by a qualified scribe ("sofer stam") who has undergone training, both in studying the relevant religious laws, and in the more practical parts, i.e. carving the quill and practising writing. The verses are written in black indelible ink with a special quill pen made either from a feather or, now quite rare, a reed. The klaf is then rolled up and placed inside the case.
