Scab in the Bible

Leviticus 13:2 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:
Leviticus 13:6-8 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. 7 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: 8 And if the priest see that, behold, the scab spreadeth in the skin, then the priest shall pronounce him unclean: it is a leprosy.
Leviticus 14:56 And for a rising, and for a scab, and for a bright spot:
Leviticus 21:20 Or crookbackt, or a dwarf, or that hath a blemish in his eye, or be scurvy, or scabbed, or hath his stones broken;
Leviticus 22:22 Blind, or broken, or maimed, or having a wen, or scurvy, or scabbed, ye shall not offer these unto the LORD, nor make an offering by fire of them upon the altar unto the LORD.
