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.

He that is to be cleansed shall wash his clothes, and shave off all his hair. The hair was specially affected by the leprosy (Leviticus 13:3; Leviticus 13:10; Leviticus 13:20; Leviticus 13:36; Leviticus 13:40). The killing of the bird and the sevenfold sprinkling of its blood upon the person of the leper implied, that though not called a sacrifice because it was not rendered in a holy place, it possessed all the characteristics of a sin offering; because the leper, thus far cleansed by the blood of atonement, was at that stage re-admissible to the camp of Israel, though not to his own tent, or to communion with God in the worship of the tabernacle.
