Leviticus 13:46

44He is a leprous man, he is unclean: the priest shall pronounce him utterly unclean; his plague is in his head.

45And the leper in whom the plague is, his clothes shall be rent, and his head bare, and he shall put a covering upon his upper lip, and shall cry, Unclean, unclean.

46All 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.

47The garment also that the plague of leprosy is in, whether it be a woollen garment, or a linen garment;

48Whether it be in the warp, or woof; of linen, or of woollen; whether in a skin, or in any thing made of skin;
