Leviticus 13:45

'The person with such an infectious disease must wear torn clothes, let his hair be unkempt, cover the lower part of his face and cry out, 'Unclean! Unclean!'

(New International Version)

'As for the leper who has the infection, his clothes shall be torn, and the hair of his head shall be uncovered, and he shall cover his mustache and cry, 'Unclean! Unclean!'

(New American Standard Bible)

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.

(King James Version)
