When a person has on the skin of his body a swelling or an eruption or a spot, and it turns into a case of leprous disease on the skin of his body, then he shall be brought to Aaron the priest or to one of his sons the priests...
#leviticus 13:2 #tazria

"He shall be brought" implies that the leper's community has a responsibility to intervene when his life conditions begin to get out of hand.

Only a Levitical priest is authorized to declare a condition to be tzaraat (biblical leprosy, which is not the same as Hansen's Disease) or a leper to be cleansed. This is why #yeshua told the leper to go to the priest after he healed him.
