Leviticus 13:31

And if the priest look on the plague of the scall, and, behold, it be not in sight deeper than the skin, and that there is no black hair in it; then the priest shall shut up him that hath the plague of the scall seven days:
29

If a man or woman have a plague upon the head or the beard;

30

Then the priest shall see the plague: and, behold, if it be in sight deeper than the skin; and there be in it a yellow thin hair; then the priest shall pronounce him unclean: it is a dry scall, even a leprosy upon the head or beard.

31

And if the priest look on the plague of the scall, and, behold, it be not in sight deeper than the skin, and that there is no black hair in it; then the priest shall shut up him that hath the plague of the scall seven days:

32

And in the seventh day the priest shall look on the plague: and, behold, if the scall spread not, and there be in it no yellow hair, and the scall be not in sight deeper than the skin;

33

He shall be shaven, but the scall shall he not shave; and the priest shall shut up him that hath the scall seven days more:

Counter-Arguments

The strongest case that this verse does not belong in this theme.

Pre-Law Clean/Unclean Distinction

This verse is found within the book of Leviticus, which details the Mosaic Law given at Sinai, and therefore describes a distinction *within* the Law, not one existing *before* it. The text itself does not provide any temporal markers to suggest these regulations predate the giving of the Law.

Symbolic / Spiritual Interpretation

The verse describes a physical examination of a skin condition ("scall") and a prescribed physical action ("shut up him that hath the plague of the scall seven days"), with no explicit or implied symbolic language for spiritual purity or moral holiness.
