'Black' in the Bible

“You are to detest these birds. They must not be eaten because they are detestable:the eagle, the bearded vulture,the black vulture,

When the priest examines the scaly infection, if it does not appear to be deeper than the skin, and there is no black hair in it, the priest must quarantine the person with the scaly infection for seven days.

But if as far as he can see, the scaly outbreak remains unchanged and black hair has grown in it, then it has healed; he is clean. The priest is to pronounce the person clean.
