Leviticus 13
44 Ref he is a leprous man, he is unclean: the priest shall surely pronounce him unclean; his plague is in his head.
45 Ref And the leper in whom the plague is, his clothes shall be rent, and the hair of his head shall go loose, and he shall cover his upper lip, and shall cry, Unclean, unclean.
46 Ref All the days wherein the plague is in him he shall be unclean; he is unclean: he shall dwell alone; without the camp shall his dwelling be.
