Leviticus 13:59 -- “This is the law of the leprous plague in a garment of wool or linen, either in the warp or woof, or in anything made of leather, to pronounce it clean or to pronounce it unclean.

Leviticus 14:1-15 -- 1 “Then the LORD spoke to Moses, saying, 2 "This shall be the law of the leper for the day of his cleansing: He shall be brought to the priest. 3 And the priest shall go out of the camp, and the priest shall examine him; and indeed, if the leprosy is healed in the leper, 4 then the priest shall command to take for him who is to be cleansed two living and clean birds, cedar wood, scarlet, and hyssop. 5 And the priest shall command that one of the birds be killed in an earthen vessel over running water. 6 As for the living bird, he shall take it, the cedar wood and the scarlet and the hyssop, and dip them and the living bird in the blood of the bird that was killed over the running water. 7 And he shall sprinkle it seven times on him who is to be cleansed from the leprosy, and shall pronounce him clean, and shall let the living bird loose in the open field. 8 He who is to be cleansed shall wash his clothes, shave off all his hair, and wash himself in water, that he may be clean. After that he shall come into the camp, and shall stay outside his tent seven days. 9 But on the seventh day he shall shave all the hair off his head and his beard and his eyebrows--all his hair he shall shave off. He shall wash his clothes and wash his body in water, and he shall be clean. 10 And on the eighth day he shall take two male lambs without blemish, one ewe lamb of the first year without blemish, three-tenths of an ephah of fine flour mixed with oil as a grain offering, and one log of oil. 11 Then the priest who makes him clean shall present the man who is to be made clean, and those things, before the LORD, at the door of the tabernacle of meeting. 12 And the priest shall take one male lamb and offer it as a trespass offering, and the log of oil, and wave them as a wave offering before the LORD. 13 Then he shall kill the lamb in the place where he kills the sin offering and the burnt offering, in a holy place; for as the sin offering is the priest's, so is the trespass offering. It is most holy. 14 The priest shall take some of the blood of the trespass offering, and the priest shall put it on the tip of the right ear of him who is to be cleansed, on the thumb of his right hand, and on the big toe of his right foot. 15 And the priest shall take some of the log of oil, and pour it into the palm of his own left hand.”

Numbers 19:17-22 -- 17 “And for an unclean person they shall take some of the ashes of the heifer burnt for purification from sin, and running water shall be put on them in a vessel. 18 A clean person shall take hyssop and dip it in the water, sprinkle it on the tent, on all the vessels, on the persons who were there, or on the one who touched a bone, the slain, the dead, or a grave. 19 The clean person shall sprinkle the unclean on the third day and on the seventh day; and on the seventh day he shall purify himself, wash his clothes, and bathe in water; and at evening he shall be clean. 20 But the man who is unclean and does not purify himself, that person shall be cut off from among the assembly, because he has defiled the sanctuary of the LORD. The water of purification has not been sprinkled on him; he is unclean. 21 It shall be a perpetual statute for them. He who sprinkles the water of purification shall wash his clothes; and he who touches the water of purification shall be unclean until evening. 22 Whatever the unclean person touches shall be unclean; and the person who touches it shall be unclean until evening.”
