Matthew Poole and continuators on Leviticus 14:8

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 dayes.

Partly to discover his perfect soundness, partly to preserve him from relapse through any seeds or relicks of it which might remain in his hair or in his clothes; and partly to teach him to put off his old lusts and to become a new man.

Out of his former habitation, in some separate place, least some of his leprosie yet lurking in him should break forth to the infection of his family.
