'Four footed' in the Bible

Every winged four-footed thing which goes on the earth is disgusting to you;

But of the winged four-footed things, those which have long legs for jumping on the earth you may have for food;

But all other winged four-footed things which go on the earth are disgusting to you.

Any four-footed beast which goes on the ball of its foot, is unclean to you: anyone touching the dead body of one of these will be unclean till evening.
