When the skin of one's body sustains a burn by fire, and the patch from the burn is a discoloration, either white streaked with red, or white, the priest shall examine it. If some hair has turned white in the discoloration, which itself appears to go deeper than the skin, it is leprosy that has broken out in the burn. The priest shall pronounce him unclean; it is a leprous affection. But if the priest finds that there is no white hair in the discoloration, and that it is not lower than the rest of the skin, and it is faded, the priest shall isolate him for seven days. On the seventh day the priest shall examine him: if it has spread in the skin, the priest shall pronounce him unclean; it is a leprous affection. But if the discoloration has remained stationary, not having spread on the skin, and it is faded, it is the swelling from the burn. The priest shall pronounce him clean, for it is the scar of the burn.
