11:3 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.
