If the priest examines it and finds that the hairs in it have not turned white and that it is not deeper than the surrounding skin, but is light in color, the priest will isolate you for seven days. If the spot spreads the priest shall pronounce you unclean. You are diseased. If it remains unchanged and does not spread, it is only the scar left from the boil. The priest will pronounce you ritually clean.
