Leviticus 13:3-5 New American Bible, Revised Edition (NABRE)

3. If the priest, upon examination of the skin’s infection, finds that the hair on the infection has turned white and the infection itself appears to be deeper than the skin, it is indeed a scaly infection; the priest, on seeing this, shall declare the person unclean.

4. If, however, the blotch on the skin is white, but does not seem to be deeper than the skin, nor has the hair turned white, the priest shall quarantine the afflicted person for seven days.

5. Should the priest, upon examination on the seventh day, find that the infection has remained unchanged in color and has not spread on the skin, the priest shall quarantine the person for another seven days.
