Leviticus 13:47-52

47“Also, if a garment has a leprous plague in it, whether it is a woolen garment or a linen garment,

48whether it is in the warp or woof of linen or wool, whether in leather or in anything made of leather,

49and 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 plague and shall be shown to the priest.

50The priest shall examine the plague and isolate that which has the plague seven days.

51And 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 an active leprosy. It is unclean.

52He shall therefore burn that garment in which is the plague, whether warp or woof, in wool or in linen, or anything of leather, for it is an active leprosy; the garment shall be burned in the fire.
