Parasha Tazria
The laws of ritual purity after childbirth and the diagnosis of tzaraat skin afflictions.
Overview
Parasha Tazria deals with two forms of ritual impurity: the impurity following childbirth and the affliction known as tzaraat — often mistranslated as leprosy but understood by the rabbis as a spiritual condition manifesting physically, caused by the sin of lashon hara (harmful speech).
The Story
A woman who gives birth undergoes a period of ritual impurity and then brings offerings to the Tabernacle. The laws of tzaraat follow: the priest examines skin afflictions and determines whether they are impure. If so, the afflicted person must dwell outside the camp, call out "impure, impure," and undergo a process of isolation and eventual purification. The affliction can also appear in garments.
Significance for Noahides
The rabbis teach that tzaraat was a divine punishment for lashon hara — speaking harmfully about others. The isolation of the afflicted person mirrors the social damage caused by harmful speech: just as the speaker separates others through their words, they are separated from the community. For Noahides, this parasha reinforces the profound moral weight of speech and the responsibility to guard one's tongue.
