Leviticus 13:33
JPS-1917וְהִ֨תְגַּלָּ֔ח וְאֶת־הַנֶּ֖תֶק לֹ֣א יְגַלֵּ֑חַ וְהִסְגִּ֨יר הַכֹּהֵ֧ן אֶת־הַנֶּ֛תֶק שִׁבְעַ֥ת יָמִ֖ים שֵׁנִֽית׃
then he shall be shaven, but the scall shall he not shave; and the priest shall shut up him that hath the scall seven days more.
Rashi Commentary
והתגלח AND HE SHALL CUT HIS HAIR around the scall, ואת הנתק לא יגלח BUT THE SCALL ITSELF HE SHALL NOT CUT THE HAIR OF — this means that he leaves a row of two hairs quite close to it around it in order that it may become discernible if it (the scall) spreads, for if it spreads it passes the hair and will extend to the spot where the hair has been cut off (Mishnah Negaim 10:5; Sifra, Tazria Parashat Nega'im, Chapter 9 7).
