Lamentations 4:15

They, namely, the people of the city meeting them, cried unto them, Depart ye! It is unclean; depart, depart, touch not! thereby applying to them the call of warning used in the case of lepers, Leviticus 13:45, lest their blood-stained garments bring defilement. When they fled away and wandered, or when they had fled away and continued as fugitives in strange lands, they said among the heathen, They shall no more sojourn there, the heathen themselves being afraid of pollution and denying the exiled and fugitive priests a retreat in their midst.
