'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 insects which are four-footed are detestable to you.

All the four-footed animals that walk on their paws are unclean for you. Whoever touches their carcasses will be unclean until evening,
