You presume but it goes into further detail my young friend, you are learning though.Leviticus:
God talked to Moses and Aaron and gave them rules about skin diseases.
[1] And the LORD spake unto Moses and Aaron, saying,


If a person has something in his skin like a sore, scab, or a spot, he should go to see Aaron or his sons the priests.
[2] When a man shall have in the skin of his flesh a rising, a scab, or a 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:


The priest will look at the skin. If the hair in the sore has changed to white, and if the sore looks deep, it is a contagious skin disease. The priest will say that the person is unclean.
[3] And the priest shall look on the plague in the skin of the flesh: and when the hair in the plague is turned white, and the plague in sight be deeper than the skin of his flesh, it is a plague of leprosy: and the priest shall look on him, and pronounce him unclean.


If the spot on his skin is white, but it is not deep, and the hair has not changed to white, he must stay away from other people for 7 days.
[4] If the bright spot be white in the skin of his flesh, and in sight be not deeper than the skin, and the hair thereof be not turned white; then the priest shall shut up him that hath the plague seven days:


On the 7th day, the priest will look at the person's skin. If the white spot has not gotten bigger or spread, the person should continue to stay away from people for 7 more days.
[5] And the priest shall look on him the seventh day: and, behold, if the plague in his sight be at a stay, and the plague spread not in the skin; then the priest shall shut him up seven days more:


The priest will check him for a third time on the 7th day. If the white spot has gotten dark and hasn't spread, then the sore was only a scab. The person should wash his clothes, and then he is clean again.
[6] 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 same scab comes back and gets bigger later, the person must see the priest again. The priest will say that he has a contagious skin disease. The person will be unclean.
[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.


If anyone has a skin problem, he must go to see the priest.
[9] When the plague of leprosy is in a man, then he shall be brought unto the priest;



If the priest sees pus in the sore, the hair in the sore is white, and the sore is raw (broken open), the priest will say that the person is unclean. But he is not contagious. He does not need to stay away from other people.
[10] And the priest shall see him: and, behold, if the rising be white in the skin, and it have turned the hair white, and there be quick raw flesh in the rising;
[11] It is an old leprosy in the skin of his flesh, and the priest shall pronounce him unclean, and shall not shut him up: for he is unclean.


If a person has a skin disease and the white skin covers all of his body, the priest will say that the person is clean
[12] And if a leprosy break out abroad in the skin, and the leprosy cover all the skin of him that hath the plague from his head even to his foot, wheresoever the priest looketh;
[13] Then the priest shall consider: and, behold, if the leprosy have covered all his flesh, he shall pronounce him clean that hath the plague: it is all turned white: he is clean.



But if the skin breaks open and it is raw, the person is unclean. The priest will look at it and say that he is unclean.
[14] But when raw flesh appeareth in him, he shall be unclean.
[15] And the priest shall see the raw flesh, and pronounce him to be unclean: for the raw flesh is unclean: it is a leprosy.


It the raw skin turns white again, the priest should look at the person again. The priest will say the person is clean again.
[16] Or if the raw flesh turn again, and be changed unto white, he shall come unto the priest;
[17] And the priest shall see him: and, behold, if the plague be turned into white; then the priest shall pronounce him clean that hath the plague: he is clean.


If a person had a boil (a deep sore) that healed, but later he sees pus in the skin again, he should go see the priest.
The priest will look at it. If the hair in the sore is white, and if the sore is deeper than the skin around it, the priest will say that the person is unclean. He has a bad skin disease that started in the boil.
[18] The flesh also, in which, even in the skin thereof, was a boil, and is healed,
[19] And in the place of the boil there be a white rising, or a bright spot, white, and somewhat reddish, and it be shewed to the priest;
[20] And if, when the priest seeth it, behold, it be in sight lower than the skin, and the hair thereof be turned white; the priest shall pronounce him unclean: it is a plague of leprosy broken out of the boil.


But if the priests sees no white hair and the sore is not deeper than the skin around it, but the skin is dark, the person should stay away from other people for 7 days.
[21] But if the priest look on it, and, behold, there be no white hairs therein, and if it be not lower than the skin, but be somewhat dark; then the priest shall shut him up seven days:


The priest will check the skin again later. If the dark skin has spread, the priest will say the person is unclean. But if the dark skin does not spread, it is not a bad skin disease. It is just an infected sore.
[22] And if it spread much abroad in the skin, then the priest shall pronounce him unclean: it is a plague.
[23] But if the bright spot stay in his place, and spread not, it is a burning boil; and the priest shall pronounce him clean.

Skin that has been burned


If a person has been burned, and the burned skin is white or reddish, he will go see the priest. The priest will look at the skin. If the hair in the burned spot is white, and the burned spot is deeper than the skin around it, the person has a bad skin disease. The priest will say he is unclean.
[24] Or if there be any flesh, in the skin whereof there is a hot burning, and the quick flesh that burneth have a white bright spot, somewhat reddish, or white;
[25] Then the priest shall look upon it: and, behold, if the hair in the bright spot be turned white, and it be in sight deeper than the skin; it is a leprosy broken out of the burning: wherefore the priest shall pronounce him unclean: it is the plague of leprosy.


But if the hair in the burned skin is not white and the burned spot is not deeper than the skin around it, but it is dark, the person must stay away from other people for 7 days. After 7 days, the priest will look at the spot again. If the darkness has spread, the priest will say the person is unclean. He has a bad skin disease. If the darkness stayed the same, the priest will say the person is clean. The darkness is from the burn and is not a bad skin disease.
[26] But if the priest look on it, and, behold, there be no white hair in the bright spot, and it be no lower than the other skin, but be somewhat dark; then the priest shall shut him up seven days:
[27] And the priest shall look upon him the seventh day: and if it be spread much abroad in the skin, then the priest shall pronounce him unclean: it is the plague of leprosy.
[28] And if the bright spot stay in his place, and spread not in the skin, but it be somewhat dark; it is a rising of the burning, and the priest shall pronounce him clean: for it is an inflammation of the burning.

Pats your head.
This is what another poster meant by how people use a book to their own advantage as you are trying to degrade your white brothers out of your personal inadequacies and hatred.
Get over that my brother, Your God frowns upon you.
