Leviticus 13:34-37

VIN(i) 34 On the seventh day, the priest shall examine the itch; and look, if the itch hasn't spread in the skin, and its appearance isn't deeper than the skin, then the priest shall pronounce him clean. He shall wash his clothes, and be clean. 35 But, if the scall do indeed spread in the skin,—after he hath been pronounced clean, 36 then the priest shall examine him; and look, if the itch has spread in the skin, the priest shall not look for the yellow hair; he is unclean. 37 But if in his eyes the itch is arrested, and black hair has grown in it; the itch is healed, he is clean. The priest shall pronounce him clean.
