Leviticus 13:37-41

But if the scall be in his sight at a stay, and that there is black hair grown up therein; the scall is healed, he is clean: and the priest shall pronounce him clean.

If a man also or a woman have in the skin of their flesh bright spots, even white bright spots;

Then the priest shall look: and, behold, if the bright spots in the skin of their flesh be darkish white; it is a freckled spot that groweth in the skin; he is clean.

And the man whose hair is fallen off his head, he is bald; yet is he clean.

And he that hath his hair fallen off from the part of his head toward his face, he is forehead bald: yet is he clean.
