'Split' in the Bible

You may eat every animal with a divided hoof those with split cloven hooves that chews the cud.

Only these ye shall not eat of those that chew the cud, or of those with hoofs cloven and split open: the camel, and the hare, and the rock-badger; for they chew the cud, but have not cloven hoofs they shall be unclean unto you;

The pig, because it has a split hoof but doesn't chew the cud, is unclean to you: of their flesh you shall not eat, and their carcasses you shall not touch.
