'Fours' in the Bible

"'Every winged swarming thing that walks on all fours is detestable to you.

However, this you may eat from all the winged swarming things that walk on all fours, which have jointed legs to hop with on the land.

All that walk on their paws among all the creatures that walk on all fours are unclean to you. Anyone who touches their carcass will be unclean until the evening,

You must not eat anything that crawls on its belly or anything that walks on all fours or on any number of legs of all the swarming things that swarm on the land, because they are detestable.
