Leviticus 11:20-28

20"All winged insects that go on all fours are detestable to you.

21Yet among the winged insects that go on all fours you may eat those that have jointed legs above their feet, with which to hop on the ground.

22Of them you may eat: the locust of any kind, the bald locust of any kind, the cricket of any kind, and the grasshopper of any kind.

23But all other winged insects that have four feet are detestable to you.

24"And by these you shall become unclean. Whoever touches their carcass shall be unclean until the evening,

25and whoever carries any part of their carcass shall wash his clothes and be unclean until the evening.

26Every animal that parts the hoof but is not cloven-footed or does not chew the cud is unclean to you. Everyone who touches them shall be unclean.

27And all that walk on their paws, among the animals that go on all fours, are unclean to you. Whoever touches their carcass shall be unclean until the evening,

28and he who carries their carcass shall wash his clothes and be unclean until the evening; they are unclean to you.
