Leviticus 13:49-51

21st Century King James Version

⁴⁹ and if the plague is greenish or reddish in the garment or in the skin, either in the warp or in the woof or in any thing of skin, it is a plague of leprosy and shall be shown unto the priest.

⁵⁰ And the priest shall look upon the plague and shut up it that hath the plague seven days.

⁵¹ And he shall look on the plague on the seventh day; if the plague is spread in the garment, either in the warp or in the woof, or in a skin or in any work that is made of skin, the plague is a consuming leprosy; it is unclean.
