Leviticus 13:19

and there should be in the place of the ulcer a white sore, or [one] looking white and bright, or fiery, and it shall be seen by the priest;

And in the place of the boil there be a white rising, or a bright spot, white, and somewhat reddish, and it be shewed to the priest;

and in the place of the boil there is a white swelling, or a bright spot, reddish-white, then it shall be shown to the priest.
