10:18. Especially, whereas none of the blood thereof hath been carried within the holy places: and you ought to have eaten it in the sanctuary, as was commanded me?
10:19. Aaron answered: This day hath been offered the victim for sin, and the holocaust before the Lord: and to me what thou seest has happened. How could I eat it, or please the Lord in the ceremonies, having a sorrowful heart?
10:20. Which when Moses had heard he was satisfied.
Leviticus Chapter 11
The distinction of clean and unclean animals.
11:1. And the Lord spoke to Moses and Aaron, saying:
11:2. Say to the children of Israel: These are the animals which you are to eat of all the living things of the earth.
Animals which you are to eat, etc… The prohibition of so many kinds of beasts, birds, and fishes, in the law, was ordered, 1st, to exercise the people in obedience, and temperance; 2ndly, to restrain them from the vices of which these animals were symbols; 3rdly, because the things here forbidden were for the most part unwholesome, and not proper to be eaten; 4thly, that the people of God, by being obliged to abstain from things corporally unclean, might be trained up to seek a spiritual cleanness.
11:3. Whatsoever hath the hoof divided, and cheweth the cud among the beasts, you shall eat.
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.
