Negative speech: this week’s parashah, Tazria-Metzora

“When a person has on their skin a swelling, a rash, or a discoloration, and it develops into a scaly affection on their skin, it shall be reported to Aaron the priest or to one of his sons, the priests” Leviticus (13:2)

Both Tazria and Metzora focus primarily on the condition of tzaraat. Commonly translated as leprosy, tzaraat is not a regular physical condition but a visible reminder of our mortality (Talmud Nedarim 64b). It renders someone tameh (impure), preventing them from entering the sanctuary and distancing them from God.

Tzaraat is a spiritual affliction manifesting as a physical one which can only be diagnosed and remedied by a Cohen (priest) rather than a medical doctor. Upon examination, the Cohen either declares the person impure or diagnoses a seven-day quarantine period leading to re-examination. The Cohen reserves judgement until then, ensuring no hasty and inappropriate conclusions.

Although there is no mention of speech here, the rabbis connect the condition to Miriam’s negative speech about Moses in Numbers where she contracts tzaraat (Exodus 4:1-7).

The Talmud teaches that “negative speech” (lashon hara) is like committing all three cardinal sins: idolatry, incest and murder. It kills three people: the one who says it, the one he or she says it about and the one who listens to it (Arachin 15b).
