Leviticus 13:45-46

⁴⁵'As to the leper in whom [is] the plague, his garments are rent, and his head is uncovered, and he covereth over the upper lip, and 'Unclean! unclean!' he calleth;

⁴⁶all the days that the plague [is] in him he is unclean; he [is] unclean, alone he doth dwell, at the outside of the camp [is] his dwelling.
