Whatsoever parts the hoof, and is cloven footed, and chews the cud, among the animals, that shall you eat.
All Commentaries on Leviticus 11:3 Go To Leviticus 11
Bede
AD 735
Hence it is properly decreed in the law that the only animals which are clean and suitable to be eaten by the people of God are those that have horns. For it is well known that those animals that chew the cud and divide the hoof are also those that have horns. So … it is mystically disclosed that the only people who can be incorporated into a spiritual union with the church of God are those who by the strength of their faith prove that they are unconquered in their battles with the vices.
