3 Bible Verses about Black Hair

And after looking at the diseased place, if it does not seem to go deeper than the skin, and there is no black hair in it, then the priest will have him shut up for seven days:

But if, in his opinion, the growth is stopped, and black hair has come up on it, the disease has gone; he is clean and the priest will say that he is clean.

You may not take an oath by your head, because you are not able to make one hair white or black.
