'Cud' in the Bible

And every beast that hath cloven hoofs, and the feet quite split open into double hoofs, and which cheweth the cud, among the beasts, that ye shall eat.

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;

and the swine, for it hath cloven hoofs, yet cheweth not the cud it shall be unclean unto you. Of their flesh shall ye not eat, and their carcase shall ye not touch.
