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
George Leo Haydock
AD 1849
Hoof divided, and cheweth the cud. The dividing the hoof, and chewing the cud, signify discretion between good and evil, and meditating on the law of God: and where either of these is wanting, a man is unclean. In like manner, fishes were reputed unclean that had not fins and scales: that is, souls that did not raise themselves up by prayer, and cover themselves with the scales of virtues, (Challoner) particularly of mortification and penance. (Worthington)
