tnHeb “the living flesh returns and is turned/changed to white.” The Hebrew verb “returns” is שׁוּב (shuv), which often functions adverbially when combined with a second verb as it is here (cf. “and is turned”) and, in such cases, is usually rendered “again” (see, e.g., GKC386–87§120.g). Another suggestion is that here שׁוּב means “to recede” (cf., e.g., 2 Kgs 20:9), so one could translate “the raw flesh recedes and turns white.” This would mean that the new “white” skin “has grown over” the raw flesh (B. A. Levine, Leviticus [JPSTC], 79).
