Leviticus 13:45-49

All the days wherein the plague shall be in him he shall be defiled; he is unclean: he shall dwell alone; without the camp shall his habitation be.

The garment also that the plague of leprosy is in, whether it be a woollen garment, or a linen garment;

Whether it be in the warp, or woof; of linen, or of woollen; whether in a skin, or in any thing made of skin;

And if the plague be greenish or reddish in the garment, or in the skin, either in the warp, or in the woof, or in any thing of skin; it is a plague of leprosy, and shall be shewed unto the priest:
