Leviticus 11:20-28

20“ ‘All flying insects that walk on all fours are to be regarded as unclean by you.

21There are, however, some flying insects that walk on all fours that you may eat: those that have jointed legs for hopping on the ground.

22Of these you may eat any kind of locust, katydid, cricket or grasshopper.

23But all other flying insects that have four legs you are to regard as unclean.

24“ ‘You will make yourselves unclean by these; whoever touches their carcasses will be unclean till evening.

25Whoever picks up one of their carcasses must wash their clothes, and they will be unclean till evening.

26“ ‘Every animal that does not have a divided hoof or that does not chew the cud is unclean for you; whoever touches the carcass of any of them will be unclean.

27Of all the animals that walk on all fours, those that walk on their paws are unclean for you; whoever touches their carcasses will be unclean till evening.

28Anyone who picks up their carcasses must wash their clothes, and they will be unclean till evening. These animals are unclean for you.
