Leviticus 13:37-39

New King James Version

³⁷ But if the scale appears to be at a standstill, and there is black hair grown up in it, the scale has healed. He is clean, and the priest shall pronounce him clean.

³⁸ “If a man or a woman has bright spots on the skin of the body, specifically white bright spots, ³⁹ then the priest shall look; and indeed if the bright spots on the skin of the body are dull white, it is a white spot that grows on the skin. He is clean.
