'Black' in the Bible

"'These you shall detest among the birds; they shall not be eaten, they are an abomination: the eagle, and the vulture, and the black vulture,

and the red kite, any kind of black kite,

If the priest examines the plague of itching, and behold, its appearance isn't deeper than the skin, and there is no black hair in it, then the priest shall isolate him the person infected with itching seven days.

But if in his eyes the itch is arrested, and black hair has grown in it; the itch is healed, he is clean. The priest shall pronounce him clean.
