Leviticus 13:49-51

BRG Bible

⁴⁹ And if the plague be 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 shewed 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 be 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 fretting leprosy; it is unclean.
