Leviticus 14:8
And he that is to be cleansed shall wash his clothes, and shave off all his hair, and wash himself in water, that he may be clean: and after that he shall come into the camp, and shall tarry abroad out of his tent seven days. And he that is to be cleansed shall wash his clothes, and shave off all his hair, and wash himself in water, that he may be clean: and after that he shall come into the camp, and shall tarry abroad out of his tent seven days.
Before this cleansing the person with leprosy was unclean and cut off from family, society, and Israel's congregation, forced to live apart and to associate only with others afflicted. Once declared clean, he was to wash his clothes, shave off all his hair, and wash himself in water, after which he might come into the camp but must tarry abroad out of his tent seven days. The priest examined him and by that decision declared him free of the disease, and so restored him to family, friends, society, and Israel's congregation.
The cleansing process also required presenting the offering commanded by Moses. This statute is part of the ceremonial laws given through Moses to govern Israel's religious life and to explain and protect the moral law. Those ordinances were sacred types that remained binding until the death of Christ, when type met antitype and their full meaning was revealed.
A man healed of leprosy was directed to follow this law by showing himself to the priest and presenting the prescribed offering. Obedience to this law showed respect for the law of Moses and the Jewish code and disproved the charge that the healing and teaching opposed it. The priest's examination and public certification of the cure made the healing a public and standing testimony to divine healing power.
