Deuteronomy 24:8

Take care , in a case of leprous disease , to be very careful to do according to all that the Levitical priests shall direct you. As I commanded them, so you shall be careful to do .

In cases of defiling skin diseases, be very careful to do exactly as the Levitical priests instruct you. You must follow carefully what I have commanded them.

Take heed in the plague of leprosy, that thou observe diligently, and do according to all that the priests the Levites shall teach you: as I commanded them, so ye shall observe to do.
