Exodus 12:22  (King James Version)
And ye shall take a bunch of hyssop, and dip it in the blood that is in the bason, and strike the lintel and the two side posts with the blood that is in the bason; and none of you shall go out at the door of his house until the morning.

a bunch
Leviticus 14:6 Leviticus 14:7 ; Numbers 19:18 ; Psalms 51:7 ; Hebrews 9:1 Hebrews 9:14 Hebrews 9:19 ; 11:28 12:24 1 Peter 1:2

The word {aizov,} which has been variously rendered, most probably denotes Hyssop; whence are derived the Chaldee {aizova,} Syriac {zupha,} Arabic {zupha,} Ethiopic {azab,} and
{hushopa,} Greek [`ussopos,] hussopos ,]
Latin {hyssopus,} German {usop,} and our hyssop, a name retained, with little variation, in all the western languages. It is a plant of the gymnospermia (naked seeded) order, belonging to the didynamia class. It has bushy stalks, growing a foot and a half high; small spear-shaped, close-sitting, and opposite leaves, with several smaller ones rising from the same joint; and all the stalks and branches terminated by erect whorled spikes of flowers, of different colours in the varieties of the plant. The leaves have an aromatic smell, and a warm, pungent taste. Its detersive, cleansing, and medicinal qualities were probably the reason why it was so particularly recommended in Scripture.* strike.
