Peter Pett's Commentary on the Bible
Leviticus 13:29-37
Dealing With Sores (Leviticus 13:29).
“And when a man or woman has a plague on the head or on the beard, then the priest shall look on the plague, and, behold, if its appearance is deeper than the skin, and there is yellow thin hair in it, then the priest shall pronounce him unclean. It is an itch. It is a suspicious skin disease of the head or of the beard.”
This is not just a ‘suspicious skin disease' but a suspected ‘plague'. It could be favus or psoriasis. The person has an itch on their head or beard. If it seems to go below the skin and there is yellowish thin hair in it, then the person is proclaimed unclean. It is a suspicious skin disease, the suspicion being that it will be permanent.
“And if the priest look on the plague, and, behold, its appearance is not deeper than the skin, and there is no black hair in it, then the priest shall shut up the one who has the plague for seven days, and on the seventh day the priest shall look on the disease, and, behold, if the itch has not spread, and there is no yellow hair in it, and the appearance of the itch is not deeper than the skin, then he shall be shaved, but will not shave the itch, and the priest shall shut up the one who has the itch for seven days more, and on the seventh day the priest shall look on the itch, and, behold, if the itch has not spread in the skin, and its appearance is not deeper than the skin, then the priest shall pronounce him clean, and he shall wash his clothes, and be clean.”
But if the plague does not go deeper than the skin, and there are no black hairs in it the person is to be quarantined for seven days, after which the priest will look at it again, and if the itch has still not spread and there are no yellowish hairs in it, and it does not go more than skin deep, the person may shave everywhere but where the itch is. Thus up to this time they have not been allowed to shave, and the men at least would be feeling very uncomfortable and shabby. But once they have shaved something of their self-confidence will be restored. This is another indication of God's concern for the details of our lives.
Then they will be quarantined for another seven days. If on this second viewing the itch has still not spread in the skin, and it does not appear to be more than skin deep, the person is pronounced clean. They must wash their clothes and will then be clean.
“But if the itch spreads abroad in the skin after his cleansing, then the priest shall look on him; and, behold, if the itch has spread in the skin, the priest shall not seek for the yellow hair, he is unclean. But if in his eyes the itch is at a standstill and black hair has grown up in it, the itch is healed, he is clean, and the priest shall pronounce him clean.”
But if the person comes back and says that the itch is spreading that is all that is required for him to be declared unclean and excluded from the camp. The priest, however, with his experience may consider that the itch has not spread, and if he sees that new black hair has grown on the itch the person will be pronounced clean.
Sin can be like an itch. And when it begins to itch it is in order to remind us to go to our great High Priest, Jesus Christ, for the itch may be the symptom of something deeper. It needs to be examined before Him so as to ensure what is its cause and that it is properly dealt with. This person may in fact have judged his own position harshly, but the priest with his experience had saved him from the consequences of his error. We too sometimes judge ourselves too harshly. How good it is then when we learn from the Master that He is satisfied with us as we are. We often think that we have become so unclean, that there is little hope for us now, but He assures us that He has dealt with any uncleanness, and that really He is pleased with our progress, and that if we will but trust Him He will see us through. He is the One Who makes holy (Hebrews 2:11). We need to be able to learn to accept forgiveness and to respond to His work within (Philippians 2:13).
