Leviticus 13:29–37

²⁹‘And when a man (or a woman) hath in him a plague in the head or in the beard, ³⁰then hath the priest seen the plague, and lo, its appearance is deeper than the skin, and in it a thin shining hair, and the priest hath pronounced him unclean; it is a scall—it is a leprosy of the head or of the beard.

³¹‘And when the priest seeth the plague of the scall, and lo, its appearance is not deeper than the skin, and there is no black hair in it, then hath the priest shut up him who hath the plague of the scall seven days.

³²‘And the priest hath seen the plague on the seventh day, and lo, the scall hath not spread, and a shining hair hath not been in it, and the appearance of the scall is not deeper than the skin, ³³then he hath shaved himself, but the scall he doth not shave; and the priest hath shut up him who hath the scall a second seven days. ³⁴And the priest hath seen the scall on the seventh day, and lo, the scall hath not spread in the skin, and its appearance is not deeper than the skin, and the priest hath pronounced him clean, and he hath washed his garments, and hath been clean.

³⁵‘And if the scall spread greatly in the skin after his cleansing, ³⁶and the priest hath seen him, and lo, the scall hath spread in the skin, the priest seeketh not for the shining hair, he is unclean; ³⁷and if in his eyes the scall hath stayed, and black hair hath sprung up in it, the scall hath been healed—he is clean—and the priest hath pronounced him clean.
