Torah, Deuteronomy 24:8: Be cautious regarding the lesion of tzara’ath, to observe meticulously and you shall do according to all that the Levite priests instruct you; as I have commanded them, [so shall you] observe.
“Lesion” and “leprosy” are the most external problems a person has because skin represents the outmost layer of egoism.
A person’s body, from inside out, is arranged as follows: marrow (Mocha), bones (Atzamot), tendons (Gidin), flesh (Basar), and skin (Or).
The eruption of lesions on the skin is the manifestation of the last degree of breakage. You must interact correctly with these problems, that is, cure yourself from leprosy through the Cohen (priest) and Levite in you, through your highest, very best corrected desires that can correct the lowest uncorrected desires in you. Otherwise, you cannot determine what this is and be cured.
