Levítico 13:45

45 "Anyone with such a defiling disease must wear torn clothes, let their hair be unkempt, Or [clothes, uncover their head] cover the lower part of their face and cry out, 'Unclean! Unclean!'

45 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.
