Leviticus 13:35-39

But if the scale spreads farther in the skin after his cleansing,

then the priest shall look at him, and if the scale has spread on the skin, the priest need not look for the yellowish hair; he is unclean.

If in his sight the scale has remained, however, and black hair has grown in it, the scale has healed, and he is clean; and the priest shall pronounce him clean.

“When a man or a woman has bright spots on the skin of the body, white bright spots,

then the priest shall look, and if the bright spots on the skin of their bodies are a faint white, it is eczema that has broken out on the skin; he is clean.
