Leviticus 11:20-24

20‘All the 1winged insects that walk on all fours are detestable to you. 21Yet these you may eat among all the 2winged insects which walk on all fours: those which have above their feet jointed legs with which to jump on the earth. 22These of them you may eat: the locust in its kinds, and the devastating locust in its kinds, and the cricket in its kinds, and the grasshopper in its kinds. 23But all other 3winged insects which are four-footed are detestable to you.

24‘By these, moreover, you will be made unclean: whoever touches their carcasses becomes unclean until evening,
