'Black' in the Bible

And when the priest seeth the plague of the scall, and lo, its appearance is not deeper than the skin, and there is no black hair in it, then hath the priest shut up him who hath the plague of the scall seven days.

and if in his eyes the scall hath stayed, and black hair hath sprung up in it, the scall hath been healed -- he is clean -- and the priest hath pronounced him clean.
