Leviticus 13:45–46

“The leprous person who has the disease shall wear torn clothes and let the hair of his head hang loose, and he shall cover his upper lip and cry out, ‘Unclean, unclean.’ He shall remain unclean as long as he has the disease. He is unclean. He shall live alone. His dwelling shall be outside the camp.

“Anyone with such a defiling disease must wear torn clothes, let their hair be unkempt, cover the lower part of their face and cry out, ‘Unclean! Unclean!’ As long as they have the disease they remain unclean. They must live alone; they must live outside the camp.

“The person who has a case of serious skin disease is to have his clothes torn and his hair hanging loose, and he must cover his mouth and cry out, ‘Unclean, unclean!’ He will remain unclean as long as he has the disease; he is unclean. He must live alone in a place outside the camp.

“Those who suffer from a serious skin disease must tear their clothing and leave their hair uncombed. They must cover their mouth and call out, ‘Unclean! Unclean!’ As long as the serious disease lasts, they will be ceremonially unclean. They must live in isolation in their place outside the camp.

“As for the person who is afflicted with a skin disease, his garments must be torn and his hair must be allowed to hang loosely, and he must cover his upper lip, and he must call out, ‘Unclean! Unclean!’ For all the days during which the infection is on him, he shall be unclean; he must live alone; his dwelling must be outside the camp.”

And 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. 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.
