Leviticus 14:2-7

²“These are the regulations regarding those who have had a skin disease when they are declared clean having been brought to the priest.

³The priest must go outside the camp and inspect the person. If the skin disease has healed,

⁴the priest shall have two ceremonially clean birds brought to him, also some cedar wood, crimson thread, and hyssop, on behalf of the person to be made clean.

⁵The priest will order one of the birds to be killed over a clay pot filled with fresh water.

⁶He will take the live bird together with the cedar wood, crimson thread, and hyssop, and dip them in the blood of the bird that was killed over the fresh water.

⁷He will use the blood to sprinkle seven times the person being made clean of the skin disease. Then the priest will declare them clean and let the live bird fly away.
