Leviticus 13:55

And the plague be not spread. — Better, though the plague hath not spread. If after the washing of the affected spot the priest finds that its appearance has not changed, it must nevertheless be burnt, since the retention of the suspicious colour indicates that it is leprosy.

It is fret inward, whether it be bare within or without. — Better, it is a corroding in the fore baldness thereof or in the back baldness thereof. (See Leviticus 13:42.) That is, though it has not spread in breadth, the distemper has eaten into the fabric, either on the upper side, which is compared to the forehead, or into the under side, which is compared to the hinder part of the head in human head-leprosy.
