Leviticus 13:49-51

New King James Version

⁴⁹ and if the plague is greenish or reddish in the garment or in the leather, whether in the warp or in the woof, or in anything made of leather, it is a leprous ^[a]plague and shall be shown to the priest. ⁵⁰ The priest shall examine the plague and isolate that which has the plague seven days. ⁵¹ And he shall examine the plague on the seventh day. If the plague has spread in the garment, either in the warp or in the woof, in the leather or in anything made of leather, the plague is ^(A)an active leprosy. It is unclean.
