Leviticus 13:46-49 New King James Version (NKJV)

46. He shall be unclean. All the days he has the sore he shall be unclean. He is unclean, and he shall dwell alone; his dwelling shall be outside the camp.

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

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

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 plague and shall be shown to the priest.
