Leviticus 13:14

But when raw flesh appeareth. — Rather, but in the day when sound flesh appeareth again, that is, whenever patches of natural flesh appear intermingled with the white scurf, he forthwith becomes unclean, since this showed that the disease had not exhausted itself. Because it is here said, “But in the day when sound flesh,” &c, and not simply “but when sound flesh,” &c., the administrators of the law in the time of Christ concluded that there were days on which the examination of this distemper was not undertaken: viz., during the seven nuptial days, and the seven days of the great pilgrim festivals of Passover and Tabernacles.
