Leviticus 13:28

But if the spot remains in one place and does not spread in the skin , but has faded , it is a swelling from the burn , and the priest shall pronounce him clean , for it is the scar of the burn .

If, however, the spot is unchanged and has not spread in the skin but has faded, it is a swelling from the burn, and the priest shall pronounce them clean; it is only a scar from the burn.

And if the bright spot stay in his place, and spread not in the skin, but it be somewhat dark; it is a rising of the burning, and the priest shall pronounce him clean : for it is an inflammation of the burning.
