Leviticus 13:47-52

47“If a fabric is contaminated with mildew — in wool or linen fabric,

48in the warp or weft of linen or wool, or in leather or anything made of leather —

49and if the contamination is green or red in the fabric, the leather, the warp, the weft, or any leather article, it is a mildew contamination and is to be shown to the priest.

50The priest is to examine the contamination and quarantine the contaminated fabric for seven days.

51The priest is to reexamine the contamination on the seventh day. If it has spread in the fabric, the warp, the weft, or the leather, regardless of how it is used, the contamination is harmful mildew; it is unclean.

52He is to burn the fabric, the warp or weft in wool or linen, or any leather article, which is contaminated. Since it is harmful mildew it must be burned.
