Leviticus 11:39-47

‘And if any animal which you may eat dies, he who touches its carcass shall be unclean until evening. He who eats of its carcass shall wash his clothes and be unclean until evening. He also who carries its carcass shall wash his clothes and be unclean until evening. ‘And every creeping thing that creeps on the earth shall be an abomination. It shall not be eaten. Whatever crawls on its belly, whatever goes on all fours, or whatever has many feet among all creeping things that creep on the earth—these you shall not eat, for they are an abomination. You shall not make yourselves abominable with any creeping thing that creeps; nor shall you make yourselves unclean with them, lest you be defiled by them. For I am the LORD your God. You shall therefore consecrate yourselves, and you shall be holy; for I am holy. Neither shall you defile yourselves with any creeping thing that creeps on the earth. For I am the LORD who brings you up out of the land of Egypt, to be your God. You shall therefore be holy, for I am holy. ‘This is the law of the animals and the birds and every living creature that moves in the waters, and of every creature that creeps on the earth, to distinguish between the unclean and the clean, and between the animal that may be eaten and the animal that may not be eaten.’ ”
