Leviticus chapter 22 verses 1-22 (written by Moses around 1350 BC) (part of the Jewish archives and now part of the Old Testament in the Christian Bible -
The Lord spoke to Moses, saying,
"2 This shall be the law of the leprous person 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 look. Then, if the case of leprous disease is healed in the leprous person, 4 the priest shall command them to take for him who is to be cleansed two live clean birds and cedarwood and scarlet yarn and hyssop....... Then he shall pronounce him clean and shall let the living bird go into the open field. 8 And he who is to be cleansed shall wash his clothes and shave off all his hair and bathe himself in water, and he shall be clean. And after that he may come into the camp, but live outside his tent seven days. 9 And on the seventh day he shall shave off all his hair from his head, his beard, and his eyebrows. He shall shave off all his hair, and then he shall wash his clothes and bathe his body in water, and he shall be clean.
10
"And on the eighth day he shall take two male lambs without blemish, and one ewe lamb a year old without blemish, and a grain offering of three tenths of an ephah of fine flour mixed with oil, and one log of oil. 11 And the priest who cleanses him shall set the man who is to be cleansed and these things before the Lord, at the entrance of the tent of meeting....... 18 And the rest of the oil that is in the priest’s hand he shall put on the head of him who is to be cleansed. Then the priest shall make atonement for him before the Lord. 19 The priest shall offer the sin offering, to make atonement for him who is to be cleansed from his uncleanness. And afterward he shall kill the burnt offering. 20 And the priest shall offer the burnt offering and the grain offering on the altar. Thus the priest shall make atonement for him, and he shall be clean.
21 "But if he is poor and cannot afford so much, then he shall take one male lamb for a guilt offering to be waved, to make atonement for him, and a tenth of an ephah of fine flour mixed with oil for a grain offering, and a log of oil; 22 also two turtledoves or two pigeons, whichever he can afford. The one shall be a sin offering and the other a burnt offering. 23 And on the eighth day he shall bring them for his cleansing to the priest, to the entrance of the tent of meeting, before the Lord....... And the rest of the oil that is in the priest’s hand he shall put on the head of him who is to be cleansed, to make atonement for him before the Lord. 30 And he shall offer, of the turtledoves or pigeons, whichever he can afford, 31 one for a sin offering and the other for a burnt offering, along with a grain offering. And the priest shall make atonement before the Lord for him who is being cleansed. 32 This is the law for him in whom is a case of leprous disease, who cannot afford the offerings for his cleansing."
