'Fours' in the Bible

All winged creeping things that go upon all fours are an abomination unto you.

Yet these may ye eat of all winged creeping things that go upon all fours, which have legs above their feet, wherewith to leap upon the earth.

And whatsoever goeth upon its paws, among all beasts that go on all fours, they are unclean unto you: whoso toucheth their carcass shall be unclean until the even.

Whatsoever goeth upon the belly, and whatsoever goeth upon all fours, or whatsoever hath many feet, even all creeping things that creep upon the earth, them ye shall not eat; for they are an abomination.
