'Infected' in the Bible

If the bright spot is white in the skin of his body, and its appearance isn't deeper than the skin, and its hair hasn't turned white, then the priest shall isolate the infected person for seven days.

"If the leprosy breaks out all over the skin, and the leprosy covers all the skin of the infected person from his head even to his feet, as far as it appears to the priest;

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.
