And you shall take a bunch of hyssop, and dip it in the blood that is in the basin, and strike the lintel and the two side posts with the blood that is in the basin; and none of you shall go out at the door of his house until the morning.
All Commentaries on Exodus 12:22 Go To Exodus 12
George Leo Haydock

Hyssop; Hebrew ezob: which some translate rosemary. (Menochius)

St. Jerome, in Isaias lxvi, says the doors were to be sprinkled in the form of a cross.
