42 And if there be in the bald head, or bald forehead, a white reddish sore; it is a leprosy sprung up in his bald head, or his bald forehead.

43 Then the priest shall look upon it: and, behold, if the rising of the sore be white reddish in his bald head, or in his bald forehead, as the leprosy appeareth in the skin of the flesh;

44 He is a leprous man, he is unclean: the priest shall pronounce him utterly unclean; his plague is in his head.

45 And the leper in whom the plague is, his clothes shall be rent, and his head bare, and he shall put a covering upon his upper lip, and shall cry, Unclean, unclean.

46 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.

In today’s verses we finally learn what was required of a person who was found to be infected with a leprosy. A person with leprosy was ritually unclean and was not to draw too near to other people, and so we see a sort of quarantine being described. The infected person was not entirely shut away from the rest of society, but he did need to live out on the fringes of the population. He could be in the same place as other Israelites, but he had to announce his approach with a cry of “unclean, unclean.” The instruction that his upper lip needed to be covered sounds like he would wear a sort of scarf or veil, functioning as a sort of olden-day medical face mask.

Going back to our analogy of a spiritually sick society, when we discover a population that has adopted a harmful ideology, we tend to lessen our connection to it. Usually, these groups are not completely eradicated, but they are kept at a distance, until their members abandon their troublesome and reintegrate with the healthy population. Examples of this might include the Hippie population and the Trans movement. We never made such organizations and ideologies illegal, but society moved apart from them, and these organizations and movements have gradually dissipated over time.

Thus, even as we recognize, call out, and distance ourselves from the ills in our society, it is with the intention of rehabilitation and reintegration, not eradication. Preventing the spread of harm is essential, but we still recognize that the infected are a part of us, and we want them to rejoin us as soon as they are clean again.
