These birds were provided by the priest for the man. They were not, like the offerings for the altar, brought by the man himself (compare Leviticus 14:4 with Leviticus 14:10), they were not presented nor brought near the sanctuary, nor was any portion of them offered on the altar.
Cedar wood, and scarlet, and hyssop - These three substances were used as the common materials in rites of purification (compare Exodus 12:22; Numbers 19:8; Psalms 51:7; Hebrews 9:19): the “cedar”, or juniper, the resin or turpentine of which was a preservative against decay, and employed in medicines for elephantiasis and other skin diseases: the “scarlet”, a “tongue,” or band, of twice-dyed scarlet wool, with which the living bird, the hyssop, and the cedar wood were tied together when they were dipped into the blood and water: the color expressing the rosiness associated with health and vital energy: and the “hyssop” (see Exodus 12:22), probably the Caper plant, whose cleansing virtues as a medicine, and use in the treatment of ulcers and diseases of the skin allied to leprosy, were known to the ancients. It has been conjectured that the scarlet band was used to tie the hyssop upon the cedar, so as to make a sort of brush, such as would be convenient for sprinkling.
