Leviticus 11:20-28

20‘All flying insects that creep on all fours shall be an abomination to you.

21Yet these you may eat of every flying insect that creeps on all fours: those which have jointed legs above their feet with which to leap on the earth.

22These you may eat: the locust after its kind, the destroying locust after its kind, the cricket after its kind, and the grasshopper after its kind.

23But all other flying insects which have four feet shall be an abomination to you.

24‘By these you shall become unclean; whoever touches the carcass of any of them shall be unclean until evening;

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

26The carcass of any animal which divides the foot, but is not cloven-hoofed or does not chew the cud, is unclean to you. Everyone who touches it shall be unclean.

27And whatever goes on its paws, among all kinds of animals that go on all fours, those are unclean to you. Whoever touches any such carcass shall be unclean until evening.

28Whoever carries any such carcass shall wash his clothes and be unclean until evening. It is unclean to you.
