Jewish tradition has placed a great deal of emphasis on purity and impurity–not in terms of hygiene, but more in a spiritual sense. There are lots of laws concerning what causes such an impurity, and what to do to contain that uncleanness.
The weekly Torah portion, Emor, addresses the Kohanim, the ancient priests and the specific laws that they were bidden to follow. Among them was that they were not to come into contact with a deceased person since this is something that imparts ritual impurity. The only exceptions were for the death of a parent, brother, unmarried sister or child. All other Israelites could tend to the bodies of the deceased within the community without concern; the Priests, however, had to be ritually pure to serve in the Tabernacle and later the Temple.
It is noteworthy that many of these ideas are on our minds today in the midst of COVID-19. We are very aware of the people with whom we come into contact. We want to know with whom they have been in contact. The questions that are asked when you enter a doctor’s office or even a supermarket parallel those that might have been asked of a priest: Are you pure? Is it safe for you to be in our midst?
The parallel isn’t exact, but the Torah demonstrates that our ancestors dealt with the same questions and uncertainty as we do today. In 2020 it is COVID-19. In ancient times, it was death in general…as well as certain skin diseases. We often read these sections of the Torah thinking how quaint their understanding of medicine was back then. How quaint will we look in a hundred years when our descendants see how we dealt with our current crisis?
