Breadcrumb: Contact uncleanliness

In Lev. 14 and 15, we are faced, yet again, by numerous examples of "contact uncleanliness." For example, if a woman is having her period, anything she lies down on, anything she sits down on, and any person she touches is considered spiritually unclean. If you touch anything that has touched her, you need to wash your own clothes and bathe, and you're still considered unclean until sunset. The same thing goes for anything that's touched semen. I can only imagine that the Israelite camp must have had a lot of people bathing and washing their clothes.
