"When a person has a burn scar in the skin that turns bright, white-reddish, or white,

if the priest examines it and indeed the hair has turned white with a white spot appearing more extensive than skin deep, it's an infectious skin disease with a burn scar that has spread. The priest is to declare him unclean. It's an infectious skin disease.

But if the bright spot remains in place, doesn't spread in the skin, and it's dull, it's the swelling of the burned area. The priest is to declare him clean, since it's the scar from a burn."
