Leviticus 14:4-6
4 the priest will order that two live clean birds,(A) cedar wood,(B) scarlet(C) yarn, and hyssop(D) be brought for the one who is to be cleansed.
5 Then the priest will order that one of the birds be slaughtered over fresh water in a clay pot.
6 He is to take the live bird together with the cedar wood, scarlet yarn, and hyssop, and dip them all into the blood of the bird that was slaughtered over the fresh water.
