'Black' in the Bible

And if the priest look on the sore of the scall, and behold, it is not in sight deeper than the skin, and there is no black hair in it, the priest shall shut up him that hath the sore of the scall seven days.

But if the scall have in his sight remained as it was, and there is black hair grown up therein, the scall is healed: he is clean; and the priest shall pronounce him clean.
