Leviticus 11:41

39“‘If any animal of which you may eat dies, he who touches its carcass shall be unclean until the evening.

40He who eats of its carcass shall wash his clothes, and be unclean until the evening. He also who carries its carcass shall wash his clothes, and be unclean until the evening.

41“‘Every creeping thing that creeps on the earth is an abomination. It shall not be eaten.

42Whatever goes on its belly, and whatever goes on all fours, or whatever has many feet, even all creeping things that creep on the earth, them you shall not eat; for they are an abomination.

43You shall not make yourselves abominable with any creeping thing that creeps. You shall not make yourselves unclean with them, that you should be defiled by them.
