Read Leviticus 13:46 Using Other Translations
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.
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 the serious disease lasts, they will be ceremonially unclean. They must live in isolation in their place outside the camp.
