Leviticus 11:25

Even of these you may eat: any kind of locust, any kind of katydid, any kind of cricket, and any kind of grasshopper.

But all winged creeping things which have four feet are an abomination to you.

“‘By these you will become unclean: whoever touches their carcass shall be unclean until the evening.

“‘Every animal which has a split hoof that isn’t completely divided, or doesn’t chew the cud, is unclean to you. Everyone who touches them shall be unclean.

Whatever goes on its paws, among all animals that go on all fours, they are unclean to you. Whoever touches their carcass shall be unclean until the evening.

He who carries their carcass shall wash his clothes, and be unclean until the evening. They are unclean to you.
