Tzara’at

Tzara'at is a biblical disease that involved discoloration of one's skin, home, or clothing. Once confirmed by a priest's inspection, it renders the subject ritually impure, requiring them to leave the camp for a period, undergo further inspection, and then a purification process. Tzara'at is the subject of Leviticus 13–14. Several biblical stories have characters inflicted with tzara'at. And tzara'at is the subject of the Mishnah's tractate Negaim.
