Leviticus 13:47-52

47“Also when a garment has a mark of tza'arat on it—whether it is a woolen or a linen garment,

48whether it is woven or textured, linen or wool, leather, or anything made from leather—

49or if the mark is greenish or reddish within the garment or in the leather, or in the weaving or the texture, or in anything made from leather, it is the plague of tza'arat and shall be shown to the kohen.

50The kohen is to examine the plague and isolate it for seven days.

51Then he is to reexamine the plague on the seventh day. If the plague has spread in the garment, either in the weaving, the texture or the leather, whatever the use for the leather may be, the plague is a destructive mildew. It is unclean.

52He is to burn the garment or the weaving, or the texture, wool or linen, or anything of leather, in which the plague resides, for it is a destructive mildew. It is to be burned in the fire.
