We are commanded regarding the ritual impurity generated by tzaraat [various discolorations described in the Torah] of a garment. This mitzvah includes all the laws associated with clothing tzaraat: under what circumstances it becomes impure, and under what circumstances it can cause impurity [to humans or other objects]; under what circumstances does the garment require the tearing out [of the discolored area], burning, washing, immersion, etc.; all that is said in the Torah and all that is stated in this regard in the oral tradition.
