Ezov
Ezov (Hebrew: אֵזוֹב, romanized: ʾēzōḇ, some English-language Bibles transliterate as ezob) is the Classical Hebrew name of a plant mentioned in the Hebrew Bible in the context of religious rituals.
Ezov is described as a small plant found on or near walls, with an aromatic odor. Maimonides, Saadia Gaon and earlier Jewish commentators identified ezov with za'atar, which principally referred to 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.
