The concept of Tzaraat is confusing.
Essentially, soon after slandering your friend, you are to be afflicted by this mysterious skin or clothing discolouration as a punishment and then excommunicated.
Doesn't this require that God intervene in nature in a very obvious way on a regular basis?
From various sources, I recall learning that God doesn't perform miracles except on the rarest of occasions - certainly not something so easily testable and routine.
How do we consolidate the disease of Tzaraat (sometimes translated as leprosy) with the concepts of free-choice, emunah, God's role in nature, etc?
