Leviticus 13:44-46

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

45And as to the leper in whom the sore is, — his garments shall be rent, and his head shall be uncovered, and he shall put a covering on his beard, and shall cry, Unclean, unclean!

46All the days that the sore shall be in him he shall be unclean: he is unclean; he shall dwell apart; outside the camp shall his dwelling be.
