Ezov
Ezov (Hebrew: אֵזוֹב, romanized: ʾēzōḇ, transliterated in some English-language Bibles as ezob) is the Classical Hebrew name of the plant Origanum syriacum mentioned in the Hebrew Bible in the context of religious rituals.
Maimonides, Saadia Gaon and earlier Jewish commentators identified ezov with the herb Origanum syriacum, which has aromatic and cleansing properties, grows wild in Israel, and can easily be bunched together to be used for sprinkling. Origanum syriacum is the primary ingredient in the spice mixture za'atar.
