바이크라 (레위기) 13:44

בראשו נגעו HIS PLAGUE IS ON HIS HEAD — I have only a statement that the following laws apply to the case of נתקין, plagues on hairy places! Whence may we learn that there are included the sufferers from all other kinds of leprous plagues? Because it states מא יטמאנו‎ט, “he shall in any case proclaim him unclean” (Sifra, Tazria Parashat Nega'im, Chapter 12 2)— thus including all of these: regarding all of these it says: “his garments shall be rent etc.”.

אִישׁ־צָר֥וּעַ ה֖וּא טָמֵ֣א ה֑וּא טַמֵּ֧א יְטַמְּאֶ֛נּוּ הַכֹּהֵ֖ן בְּרֹאשׁ֥וֹ נִגְעֽוֹ׃

he is diseased, he is unclean: the priest shall pronounce him utterly unclean; his plague is in his head.
