3. Mose 13:53

If the mole had not spread during the seven days, the priest was to cause the fabric in which the mole appeared to be washed, and then shut it up for seven days more. If the mole did not alter its appearance after being washed, even though it had not spread, the fabric was unclean, and was therefore to be burned. "It is a corroding in the back and front" (of the fabric of leather). פּחתת, from פּחת, in Syriac fodit, from which comes פּחת a pit, lit., a digging: here a corroding depression. קרחת a bald place in the front or right side, גּבּחת a bald place in the back or left side of the fabric or leather.

The next ceremonial uncleanness is that of the leprosy, concerning which the law was very large and particular; we have the discovery of it in this chapter, and the cleansing of the leper in the next. Scarcely any one thing in all the levitical law takes up so much room as this. I. Rules are here given by which the priest must judge whether the man had the leprosy or no, according as the symptom was that appeared. 1. If it was a swelling, a scab, or a bright spot (v. 1-17). 2. If it was a bile (Lev 13:18-23). 3. If it was in inflammation (Lev 13:24-28). 4. If it was in the head or beard (Lev 13:29-37). 5. If it was a bright spot (Lev 13:38, Lev 13:39). 6. If it was in a bald head (Lev 13:40-44). II. Direction is given how the leper must be disposed of (Lev 13:45, Lev 13:46). III. Concerning the leprosy in garments (Lev 13:47, etc.).
