Leviticus 11:21-25

21You may, however, eat winged insects that walk along the ground and have jointed legs so they can jump.

22The insects you are permitted to eat include all kinds of locusts, bald locusts, crickets, and grasshoppers.

23All other winged insects that walk along the ground are detestable to you.

24“The following creatures will make you ceremonially unclean. If any of you touch their carcasses, you will be defiled until evening.

25If you pick up their carcasses, you must wash your clothes, and you will remain defiled until evening.
