'Ruminate' in the Bible

except you are not to eat the following animals that have divided hooves or ruminate their cud: the camel (because it chews the cud but doesn't have divided hooves, it is to be unclean for you),

and the pig (because it has divided hooves and is therefore cloven-footed, but it doesn't ruminate its cud, it is to be unclean for you).
