Leviticus 13:46

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 .

As long as they have the disease they remain unclean. They must live alone; they must live outside the camp.

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 .
