Vayikra 13:10

ומחית A QUICK [RAW FLESH] — sainement in old French English healing; — it means that the part of the white within the “higher-lying white spot” (השאת) has turned to a flesh-colour; this, too, is a symptom of uncleanness; — white hair without healthy flesh, and healthy flesh without white hair . Although healthy flesh is mentioned only in connection with a spot of higher-lying colour, in the case of all pure white colours (snow-white and wool-white) and their shades (lit., derivations) it is also a symptom of uncleanness(cf. Sifra, Tazria Parashat Nega'im, Section 3 1; Mishnah Negaim 4:6).

and the priest shall see him: and, behold, if a white swelling be in the skin, and it have turned the hair white, and there be quick raw flesh in the rising;
