'Scab' in the Bible

When a man shall have in the skin of his flesh a rising, a scab, or bright spot, and it be in the skin of his flesh like the plague of leprosy; then he shall be brought unto Aaron the priest, or unto one of his sons the priests:

And the priest shall look on him again the seventh day: and, behold, if the plague be somewhat dark, and the plague spread not in the skin, the priest shall pronounce him clean: it is but a scab: and he shall wash his clothes, and be clean.

But if the scab spread much abroad in the skin, after that he hath been seen of the priest for his cleansing, he shall be seen of the priest again:

And if the priest see that, behold, the scab spreadeth in the skin, then the priest shall pronounce him unclean: it is a leprosy.

If the scab remains in place and doesn't spread, then it's the scab from the boil. The priest is to declare him clean."

When the priest examines the skin rash on the seventh day and finds that indeed the scab did not spread, there's no yellowish hair on it, and the scales don't appear more extensive than skin deep,

then he is to be shaven, but the scab is not to be shaved off. The priest is to isolate him a second time for seven days.

The priest is to examine the scab on the seventh day. If, indeed, the scab hasn't spread on the skin and it doesn't appear more extensive than skin deep, then the priest is to declare him clean. He is to wash his garments and be clean.

If, in his opinion, the scab remained the same and a black hair grew in it, then the scab has healed. He's clean. The priest is to declare him clean.

And for a rising, and for a scab, and for a bright spot:

The LORD will smite thee with the botch of Egypt, and with the emerods, and with the scab, and with the itch, whereof thou canst not be healed.

Therefore the Lord will smite with a scab the crown of the head of the daughters of Zion, and the LORD will discover their secret parts.
