Leviticus 14:3-9

3The priest is to go outside the camp to examine him, and if the skin disease of the afflicted person has healed, 4the priest shall order that two live clean birds, cedar wood, scarlet yarn, and hyssop be brought for the one to be cleansed.

5Then the priest shall command that one of the birds be slaughtered over fresh water1 in a clay pot. 6And he is to take the live bird together with the cedar wood, scarlet yarn, and hyssop, and dip them into the blood of the bird that was slaughtered over the fresh water. 7Seven times he shall sprinkle the one to be cleansed of the skin disease. Then he shall pronounce him clean and release the live bird into the open field.

8The one being cleansed must wash his clothes, shave off all his hair, and bathe with water; then he will be ceremonially clean. Afterward, he may enter the camp, but he must remain outside his tent for seven days. 9On the seventh day he must shave off all his hair—his head, his beard, his eyebrows, and the rest of his hair. He must wash his clothes and bathe himself with water, and he will be clean.
