Leviticus 13:24-28 - A Burn On The Skin
24 In case any of you have been burned. If the raw flesh becomes white or reddish-white, 25 the priest will examine it. If the hair on the affected area has turned white and the affected area looks deeper than the rest of the skin, an infectious skin disease has developed in the burn. The priest will pronounce you unclean. It is an infectious skin disease. 26 But if the priest examines it and the hair in it is not white and the affected area is not deeper than the rest of the skin but has faded, the priest must put you in isolation for seven days. 27 The priest will examine you again on the seventh day. If it is spreading it is a dreaded skin disease. The priest will pronounce you unclean. 28 If the spot remains unchanged and does not spread and is light in color, it is not a dreaded skin disease. The priest will pronounce you ritually clean, because it is only a scar from the burn.
