the healed area of the burn: Saynement [in Old French]. When the burn healed, the area changed to become a blended bahereth [of white and red], or pure white one. The signs of a burn (מִכְוָה) and the signs of an inflammation (שְׁחִין) are the same. [If so,] why does Scripture separate them [into two sections]? To teach us that they do not become combined with each other, [i.e., while a griss, the area of a bean, is the minimum surface area of a lesion for it to be deemed unclean,] if a lesion the size of half a griss emerges in an inflammation, and [another] the size of half a griss in a burn, they are not judged as [though] a full griss [of lesion has emerged]. — [Chul. 8a]
מחית המכוה: שיינימנ"ט בלע"ז [רפוי] כשחיתה המכוה נהפכה לבהרת פתוכה או לבנה חלקה. וסימני מכוה וסימני שחין שוים הם, ולמה חלקן הכתוב, לומר שאין מצטרפין זה עם זה, נולד חצי גריס בשחין וחצי גריס במכוה לא ידונו כגריס:
25the kohen shall look at it. And, behold! the hair has turned white in the bahereth, and its appearance is deeper than the skin, it is tzara'ath which has spread in the burn. So, the kohen shall pronounce him unclean. It is a lesion of tzara'ath.
26But, if the kohen looks at it, and, behold! there is no white hair in the bahereth, and it is not lower than the skin and it is dim, the kohen shall quarantine him for seven days.
28But if the bahereth remains in its place, not increasing on the skin, and it is dim, it is a se'eith of the burn, and the kohen shall pronounce him clean, because it is the scar tissue of the burn.
