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
Richard Challoner
AD 1781
Hoof divided, and cheweth the cud: The dividing of the hoof and chewing of 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 virtue.
