wheresoever the priest looketh; that is, he cannot look any where upon any part of him but he sees the signs of the leprosy on him; and from whence the Jewish writers gather, that a priest that inspects leprous persons ought to have a clear sight, and to have both his eyes, and that the inspection should not be made in a dark house.
