Leviticus 13:2-3

NSB(i) 2 »If any of you have a sore on your skin or a boil or an inflammation that could develop into a dreaded skin disease, you shall be brought to the priest. 3 »The priest will examine the sore. If the hairs in it have turned white and the sore appears to be deeper than the surrounding skin, it is a dreaded skin disease, and the priest will pronounce you unclean.
