||'You will then have to take a bunch of hyssop and dip it into the blood that [will be placed] in a basin. Touch the beam over the door and the two doorposts with some of the blood in the basin. Not a single one of you may go out the door of his house until morning.

(Septuagint; Bertenoro, Rabbi Yitzchak ben Malkhi-tzedek, on Shevi'ith 8:1). Ezov in Hebrew, cognate to the English. This is a form of wild middle eastern marjoram (marjorna syriaca or origanum maru). It is a low plant, a little over a foot high, with blue blossoms. The Mishnah describes it as having woody lower parts, with branches growing sideways, containing at least three buds on top (Parah 11:8,9). Although it grew wild, it was also cultivated as a spice (Maasroth 3:9). It is an aromatic spice with deodorizing properties (Ibn Ezra). Some authorities identify the ezov with the caper plant (caparis spinosa), or with wild thyme or oregano (Rambam on Shevi'ith 8:1, Nega'im 14:6; Me'Am Loez; cf. Shabbath 109b; Arukh).
