Leviticus 14:4-6

New Catholic Bible

⁴ the priest will order that two live, clean birds, cedar wood, scarlet yarn, and hyssop be brought to the person who is to be cleansed. ⁵ The priest shall order that one of the birds be killed over fresh water that is in a clay pot. ⁶ He is to take the live bird and dip the cedar wood, the scarlet yarn, the hyssop, and the live bird in the blood of the bird that was killed over the fresh water.
