Leviticus 13:59

This [is] the law of the plague of leprosy,.... The rules by which it was to be judged of; whether or no it was

in a garment of woollen, or linen, either the warp or woof, or any thing of skins; which include everything in which this sort of leprosy was:

to pronounce it clean, or to pronounce it unclean; either to declare it free from the plague of the leprosy, or as infected with it, and so accordingly dispose of it.
