²⁶ "Every animal that has a split hoof that's not completely divided, or that doesn't chew the cud is unclean for you; if you touch the carcass of any of them you become unclean.^27-28 "Every four-footed animal that goes on its paws is unclean for you; if you touch its carcass you are unclean until evening. If you pick up its carcass you must wash your clothes and are unclean until evening. They are unclean for you.^29-38 "Among the creatures that crawl on the ground, the following are unclean for you: weasel, rat, all lizards, gecko, monitor lizard, wall lizard, skink, chameleon. Among the crawling creatures, these are unclean for you. If you touch them when they are dead, you are ritually unclean until evening. When one of them dies and falls on something, that becomes unclean no matter what it's used for, whether it's made of wood, cloth, hide, or sackcloth. Put it in the water—it's unclean until evening, and then it's clean. If one of these dead creatures falls into a clay pot, everything in the pot is unclean and you must break the pot. Any food that could be eaten but has water on it from such a pot is unclean, and any liquid that could be drunk from it is unclean. Anything that one of these carcasses falls on is unclean—an oven or cooking pot must be broken up; they're unclean and must be treated as unclean. A spring, though, or a cistern for collecting water remains clean, but if you touch one of these carcasses you're ritually unclean. If a carcass falls on any seeds that are to be planted, they remain clean. But if water has been put on the seed and a carcass falls on it, you must treat it as unclean.^39-40 "If an animal that you are permitted to eat dies, anyone who touches the carcass is ritually unclean until evening. If you eat some of the carcass you must wash your clothes and you are unclean until evening. If you pick up the carcass you must wash your clothes and are unclean until evening.^41-43 "Creatures that crawl on the ground are detestable and not to be eaten. Don't eat creatures that crawl on the ground, whether on their belly or on all fours or on many feet—they are detestable. Don't make yourselves unclean or be defiled by them, because I am your God.^44-45 "Make yourselves holy for I am holy. Don't make yourselves ritually unclean by any creature that crawls on the ground. I am God who brought you up out of the land of Egypt. Be holy because I am holy.^46-47 "These are the instructions on animals, birds, fish, and creatures that crawl on the ground. You have to distinguish between the ritually unclean and the clean, between living creatures that can be eaten and those that cannot be eaten."
