“Then the priest shall look upon it: and, behold, if the rising of the sore be white reddish in his bald head, or in his bald forehead, as the leprosy appeareth in the skin of the flesh;”
King James Version (KJV)
13:42 It is a leprosy - It is a sign that such baldness came not from age, or any accident, but from the leprosy.
13:45 His clothes shall be rent - In the upper and fore parts, which were most visible. This was done partly as a token of sorrow, because though this was not a sin, yet it was an effect of sin, and a sore punishment, whereby he was cut off both from converse with men, and from the enjoyment of God in his ordinances; partly as a warning to others to keep at a due distance from him wheresoever he came. And his head bare - Another sign of mourning. God would have men though not overwhelmed with, yet deeply sensible of his judgments. A covering on his upper lip - Partly as another badge of his sorrow and shame, and partly for the preservation of others from his breath or touch. Unclean, unclean - As begging the pity and prayers of others, and confessing his own infirmity, and cautioning those who came near him, to keep at a distance from him.
