Leviticus 11:20-23
20 “‘All flying insects that walk on all fours are to be detestable to you.
21 There are, however, some winged creatures that walk on all fours that you may eat: those that have jointed legs for hopping on the ground.
22 Of these you may eat any kind of locust, katydid, cricket or grasshopper.
23 But all other winged creatures that have four legs you are to detest.
