Holiness in Judaism

Holiness in Judaism, often referred to by the Hebrew word for holiness, Kedushah (Hebrew: קְדֻשָּׁה), is frequently used in Judaism to describe God; worldly places and items that have holy status, such as a Torah, other Torah literature, and Jewish ritual objects such as a menorah, tzitzit, tefillin, or mikveh; special days of the year; and people who are considered on a high spiritual level (a tzadik or a gadol).

[1] The Torah describes the Aaronite priests and the Levites as being selected by God to perform the Temple services; they, as well, are called "holy."

Work is not allowed on those days, and rabbinic tradition lists 39 categories of activity that are specifically prohibited.

Any personal possession may be dedicated to the Temple of God, after which its misappropriation is considered among the gravest of sins.

Those that may be eaten have very specific rules concerning who may eat which of their parts, and time limits on when the consumption must be completed.
