¹⁹ If there is still a red or white mark on the skin, the person must go to the priest. ²⁰ The priest must look at the person's skin. The red mark might be under the skin and the hair on the skin might be white. Then the priest must say that the person has a disease. The person is not clean. ²¹ If the red mark is not under the skin, it might not be a bad disease. There may not be any white hair on the red mark and the mark may be less red. If that is true, it might not be a bad disease. The priest must keep the person separate from the people for seven days.
