Leviticus 11:20-21, 41-42

“ ‘All flying insects that walk on all fours are to be regarded as unclean by you. There are, however, some flying insects that walk on all fours that you may eat: those that have jointed legs for hopping on the ground.

“ ‘Every creature that moves along the ground is to be regarded as unclean; it is not to be eaten. You are not to eat any creature that moves along the ground, whether it moves on its belly or walks on all fours or on many feet; it is unclean.
