New International Version - UK
41 ‘“Every creature that moves along the ground is to be regarded as unclean; it is not to be eaten. 42 You are not to eat any creature that moves along the ground, whether it moves on its belly or walks on all fours or on many feet; it is unclean. 43 Do not defile yourselves by any of these creatures. Do not make yourselves unclean by means of them or be made unclean by them. 44 I am the Lord your God; consecrate yourselves and be holy, because I am holy. Do not make yourselves unclean by any creature that moves along the ground. 45 I am the Lord, who brought you up out of Egypt to be your God; therefore be holy, because I am holy.
46 ‘“These are the regulations concerning animals, birds, every living thing that moves about in the water and every creature that moves along the ground. 47 You must distinguish between the unclean and the clean, between living creatures that may be eaten and those that may not be eaten.”’
Purification after childbirth
12 The Lord said to Moses, 2 ‘Say to the Israelites: “A woman who becomes pregnant and gives birth to a son will be ceremonially unclean for seven days, just as she is unclean during her monthly period. 3 On the eighth day the boy is to be circumcised. 4 Then the woman must wait thirty-three days to be purified from her bleeding. She must not touch anything sacred or go to the sanctuary until the days of her purification are over. 5 If she gives birth to a daughter, for two weeks the woman will be unclean, as during her period. Then she must wait sixty-six days to be purified from her bleeding.
6 ‘“When the days of her purification for a son or daughter are over, she is to bring to the priest at the entrance to the tent of meeting a year-old lamb for a burnt offering and a young pigeon or a dove for a sin offering.[a] 7 He shall offer them before the Lord to make atonement for her, and then she will be ceremonially clean from her flow of blood.
‘“These are the regulations for the woman who gives birth to a boy or a girl. 8 But if she cannot afford a lamb, she is to bring two doves or two young pigeons, one for a burnt offering and the other for a sin offering. In this way the priest will make atonement for her, and she will be clean.”’
Regulations about defiling skin diseases
13 The Lord said to Moses and Aaron, 2 ‘When anyone has a swelling or a rash or a shiny spot on their skin that may be a defiling skin disease,[b] they must be brought to Aaron the priest or to one of his sons[c] who is a priest. 3 The priest is to examine the sore on the skin, and if the hair in the sore has turned white and the sore appears to be more than skin deep, it is a defiling skin disease. When the priest examines that person, he shall pronounce them ceremonially unclean. 4 If the shiny spot on the skin is white but does not appear to be more than skin deep and the hair in it has not turned white, the priest is to isolate the affected person for seven days. 5 On the seventh day the priest is to examine them, and if he sees that the sore is unchanged and has not spread in the skin, he is to isolate them for another seven days. 6 On the seventh day the priest is to examine them again, and if the sore has faded and has not spread in the skin, the priest shall pronounce them clean; it is only a rash. They must wash their clothes, and they will be clean. 7 But if the rash does spread in their skin after they have shown themselves to the priest to be pronounced clean, they must appear before the priest again. 8 The priest is to examine that person, and if the rash has spread in the skin, he shall pronounce them unclean; it is a defiling skin disease.
9 ‘When anyone has a defiling skin disease, they must be brought to the priest. 10 The priest is to examine them, and if there is a white swelling in the skin that has turned the hair white and if there is raw flesh in the swelling, 11 it is a chronic skin disease and the priest shall pronounce them unclean. He is not to isolate them, because they are already unclean.
12 ‘If the disease breaks out all over their skin and, so far as the priest can see, it covers all the skin of the affected person from head to foot, 13 the priest is to examine them, and if the disease has covered their whole body, he shall pronounce them clean. Since it has all turned white, they are clean. 14 But whenever raw flesh appears on them, they will be unclean. 15 When the priest sees the raw flesh, he shall pronounce them unclean. The raw flesh is unclean; they have a defiling disease. 16 If the raw flesh changes and turns white, they must go to the priest. 17 The priest is to examine them, and if the sores have turned white, the priest shall pronounce the affected person clean; then they will be clean.
18 ‘When someone has a boil on their skin and it heals, 19 and in the place where the boil was, a white swelling or reddish-white spot appears, they must present themselves to the priest. 20 The priest is to examine it, and if it appears to be more than skin deep and the hair in it has turned white, the priest shall pronounce that person unclean. It is a defiling skin disease that has broken out where the boil was. 21 But if, when the priest examines it, there is no white hair in it and it is not more than skin deep and has faded, then the priest is to isolate them for seven days. 22 If it is spreading in the skin, the priest shall pronounce them unclean; it is a defiling disease. 23 But if the spot is unchanged and has not spread, it is only a scar from the boil, and the priest shall pronounce them clean.
