'Four' in the Bible

and any winged insect that crawls on four legs is detestable for you.

However, you may eat winged creatures that crawl on four legs that extend over its head and by which it hops on the ground.

But any other winged insect that has four legs is detestable for you

Among the animals, anything that walks on their paws and on four legs is unclean for you. Anyone who touches their carcasses becomes unclean until evening.

You are not to eat anything that crawls on its belly, anything that walks on four legs, anything that has many legs, or any of the swarming creatures that swarm the land, because they're detestable.
