“And in the seventh day the priest shall look on the scall: and, behold, if the scall be not spread in the skin, nor be in sight deeper than the skin; then the priest shall pronounce him clean: and he shall wash his clothes, and be clean.”
King James Version (KJV)
13:33 He shall be shaven - For the more certain discovery of the growth or stay of the plague.
13:36 He shall not seek - He need not search for the hair, or any other sign, the spreading of it being a sure sign of leprosy.
