Seeing the full picture
ואם-פרוח תפרח הצרעת בעור וכסתה הצרעת את כל-עור הנגע מראשו ועד-רגליו לכל-מראה עיני הכהן
If the tzra’as spreads on the skin and the tzara’as covers the entire skin, from his head to his feet, the full view of the Kohen
This week’s double parsha mostly deals with the laws of tzara’as, most commonly translated as leprosy. While being a whitish skin condition, in reality it’s a totally unrelated spiritual malady with physical symptoms. Chazal tell us that someone who contracts tzara’as, known as a Metzora, usually committed a certain sin. One example is that of loshon hara, evil speech. As a result of his sin, he is infected with a disturbing skin condition, and has to have his status established by a Kohen. If the Kohen determines he is spiritually pure, then he is. The opposite is also true.
