1 And the LORD spake unto Moses and to Aaron, saying unto them, 2 Speak unto the children of Israel, saying, These are the beasts which ye shall eat among all the beasts that are on the earth. 3 Whatsoever parteth the hoof, and is clovenfooted, and cheweth the cud, among the beasts, that shall ye eat. 4 Nevertheless these shall ye not eat of them that chew the cud, or of them that divide the hoof: as the camel, because he cheweth the cud, but divideth not the hoof; he is unclean unto you. 5 And the coney, because he cheweth the cud, but divideth not the hoof; he is unclean unto you. 6 And the hare, because he cheweth the cud, but divideth not the hoof; he is unclean unto you. 7 And the swine, though he divide the hoof, and be clovenfooted, yet he cheweth not the cud; he is unclean to you. 8 Of their flesh shall ye not eat, and their carcase shall ye not touch; they are unclean to you. 9 These shall ye eat of all that are in the waters: whatsoever hath fins and scales in the waters, in the seas, and in the rivers, them shall ye eat. 10 And all that have not fins and scales in the seas, and in the rivers, of all that move in the waters, and of any living thing which is in the waters, they shall be an abomination unto you: 11 They shall be even an abomination unto you; ye shall not eat of their flesh, but ye shall have their carcases in abomination. 12 Whatsoever hath no fins nor scales in the waters, that shall be an abomination unto you. 13 And these are they which ye shall have in abomination among the fowls; they shall not be eaten, they are an abomination: the eagle, and the ossifrage, and the ospray, 14 And the vulture, and the kite after his kind; 15 Every raven after his kind; 16 And the owl, and the night hawk, and the cuckow, and the hawk after his kind, 17 And the little owl, and the cormorant, and the great owl, 18 And the swan, and the pelican, and the gier eagle, 19 And the stork, the heron after her kind, and the lapwing, and the bat. 20 All fowls that creep, going upon all four, shall be an abomination unto you. 21 Yet these may ye eat of every flying creeping thing that goeth upon all four, which have legs above their feet, to leap withal upon the earth; 22 Even these of them ye may eat; the locust after his kind, and the bald locust after his kind, and the beetle after his kind, and the grasshopper after his kind. 23 But all other flying creeping things, which have four feet, shall be an abomination unto you. 24 And for these ye shall be unclean: whosoever toucheth the carcase of them shall be unclean until the even. 25 And whosoever beareth ought of the carcase of them shall wash his clothes, and be unclean until the even. 26 The carcases of every beast which divideth the hoof, and is not clovenfooted, nor cheweth the cud, are unclean unto you: every one that toucheth them shall be unclean. 27 And whatsoever goeth upon his paws, among all manner of beasts that go on all four, those are unclean unto you: whoso toucheth their carcase shall be unclean until the even. 28 And he that beareth the carcase of them shall wash his clothes, and be unclean until the even: they are unclean unto you. 29 These also shall be unclean unto you among the creeping things that creep upon the earth; the weasel, and the mouse, and the tortoise after his kind, 30 And the ferret, and the chameleon, and the lizard, and the snail, and the mole. 31 These are unclean to you among all that creep: whosoever doth touch them, when they be dead, shall be unclean until the even. 32 And upon whatsoever any of them, when they are dead, doth fall, it shall be unclean; whether it be any vessel of wood, or raiment, or skin, or sack, whatsoever vessel it be, wherein any work is done, it must be put into water, and it shall be unclean until the even; so it shall be cleansed. 33 And every earthen vessel, whereinto any of them falleth, whatsoever is in it shall be unclean; and ye shall break it. 34 Of all meat which may be eaten, that on which such water cometh shall be unclean: and all drink that may be drunk in every such vessel shall be unclean. 35 And every thing whereupon any part of their carcase falleth shall be unclean; whether it be oven, or ranges for pots, they shall be broken down: for they are unclean, and shall be unclean unto you. 36 Nevertheless a fountain or pit, wherein there is plenty of water, shall be clean: but that which toucheth their carcase shall be unclean. 37 And if any part of their carcase fall upon any sowing seed which is to be sown, it shall be clean. 38 But if any water be put upon the seed, and any part of their carcase fall thereon, it shall be unclean unto you. 39 And if any beast, of which ye may eat, die; he that toucheth the carcase thereof shall be unclean until the even. 40 And he that eateth of the carcase of it shall wash his clothes, and be unclean until the even: he also that beareth the carcase of it shall wash his clothes, and be unclean until the even. 41 And every creeping thing that creepeth upon the earth shall be an abomination; it shall not be eaten. 42 Whatsoever goeth upon the belly, and whatsoever goeth upon all four, or whatsoever hath more feet among all creeping things that creep upon the earth, them ye shall not eat; for they are an abomination. 43 Ye shall not make yourselves abominable with any creeping thing that creepeth, neither shall ye make yourselves unclean with them, that ye should be defiled thereby. 44 For I am the LORD your God: ye shall therefore sanctify yourselves, and ye shall be holy; for I am holy: neither shall ye defile yourselves with any manner of creeping thing that creepeth upon the earth. 45 For I am the LORD that bringeth you up out of the land of Egypt, to be your God: ye shall therefore be holy, for I am holy. 46 This is the law of the beasts, and of the fowl, and of every living creature that moveth in the waters, and of every creature that creepeth upon the earth: 47 To make a difference between the unclean and the clean, and between the beast that may be eaten and the beast that may not be eaten.
[AD 1781] Richard Challoner on Leviticus 11:2
Animals which you are to eat: The prohibition of so many kinds of beasts, birds, and fishes, in the law, was ordered, 1 st, to exercise the people in obedience, and temperance; 2 ndly, to restrain them from the vices of which these animals were symbols; 3 rdly, because the things here forbidden were for the most part unwholesome, and not proper to be eaten; 4 thly, that the people of God, by being obliged to abstain from things corporally unclean, might be trained up to seek a spiritual cleanness.
[AD 215] Clement of Alexandria on Leviticus 11:3
With whom then should we live? With the just, he replies, again under a metaphor. Everything “of split hoof and chewing the cud” is clean, because the split hoof obviously is a sign of evenly balanced justice, which chews the cud of its own food of justice, the word, which enters from without through instruction. And, once within, [it] is recalled as if from the stomach of the mind for the musings of reason. The just man chews the cud of spiritual nourishment, because he holds the Word in his mouth. Justice undoubtedly divides the hoof, in that it both sanctifies in this life and prepares us as well for the life to come.

[AD 253] Origen of Alexandria on Leviticus 11:3
[In Songs], the bride desires to sit down in the shadow of this apple tree. This prefigures either the church, as we said, under the protection of the Son of God, or else the soul fleeing all other teachings and cleaving to the Word of God alone. She chews the Word, whose fruit, moreover, she finds sweet in her throat by continual meditation on the law of God, chewing as if it were like the cud of a clean animal.

[AD 735] Bede on Leviticus 11:3
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.

[AD 1781] Richard Challoner on Leviticus 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.
[AD 215] Clement of Alexandria on Leviticus 11:4-13
The all-wise Educator, by the lips of Moses, compared association with corrupt men to living with swine when he forbade the ancient people to partake of swine. He made it plain in those words that they who invoke God should not seek the company of the unclean who, like swine, revel in bodily pleasures and filthy habits of life and impure delights, itching for evil-minded pleasures of sex.

[AD 215] Clement of Alexandria on Leviticus 11:4-13
He adds too that they are not to eat “kite or mastophage or eagle,” meaning “You shall not go near those who make their livelihood by plundering others.” He says other similar things under some sort of allegory.

[AD 215] Clement of Alexandria on Leviticus 11:4-13
It is then proper that the barbarian philosophy, on which it is our business to speak, should prophesy also obscurely and by symbols, as was evinced. Such are the injunctions of Moses: “These common things, the sow, the hawk, the eagle and the raven, are not to be eaten.” For the sow is the emblem of voluptuous and unclean lust of food and lecherous and filthy licentiousness in venery, always prurient, and material, and lying in the mire and fattening for slaughter and destruction.

[AD 258] Novatian on Leviticus 11:4-13
Fish with rough scales are considered clean, just as persons with austere, rough, unpolished, steadfast and grave traits are commended. Fish without scales are considered unclean, just as loose, fickle, insincere and effeminate traits are censured. What does the law mean when it states, “You shall not eat the camel”? From the example of an animal, it censures an unruly life and one distorted by unpleasantness. What does the law mean when it forbids one to partake of the flesh of swine? It condemns, you can be sure, a foul and filthy life—one that delights in sordid vices by placing its supreme good not in nobility of spirit but in the flesh alone. What does the law want to indicate when it forbids the hare? It denounces nervous, effeminate men. Who would use as food the flesh of the weasel? In it the law condemns theft.Who would dare partake of the skink? The law abhors a capricious and fickle life. Who would eat the newt? The law detests aberrations of the mind. Who would dare partake of the hawk, the kite or the eagle? The law hates marauders and those who live by violence. Who does not loathe the vulture? The law execrates those who look for booty in someone else’s death. Who would eat the crow? The law detests immoral and shady intentions. When the law prohibits ostrich, it disapproves of intemperance. When it condemns the nightjar, it hates those who shun the light of truth. When it bans the swan, it loathes stiff-necked pride. When it excludes the heron, it dislikes a garrulous and undisciplined tongue. When it detests the bat, it condemns those who seek out the darkness of error that is like night. The law execrates these and similar characteristics in animals. Since the animals, however, are born with such characteristics, they are without reproach. Conversely such qualities are reprehensible in humanity, which was not created with them but learns from them by comparison with contrary nature, through the exercise of their own error.

[AD 604] Gregory the Dialogist on Leviticus 11:4-13
Believing people are forbidden to use fish without its fins for food. Fish with fins and scales even leap up above the water. What do the fish with fins represent if not chosen souls? They alone pass over into the body of the heavenly church.

[AD 1781] Richard Challoner on Leviticus 11:5
The cherogrillus: Some suppose it to be the rabbit, others the hedgehog. St. Jerome intimates that it is another kind of animal common in Palestine, which lives in the holes of rocks or in the earth. We choose here, as also in the names of several other creatures that follow (which are little known in this part of the world,) to keep the Greek or Latin names.
[AD 1781] Richard Challoner on Leviticus 11:13
The griffon: Not the monster which the painter represent, which hath no being upon earth; but a bird of the eagle kind, larger than the common.
[AD 65] 1 Peter on Leviticus 11:44-45
Wherefore gird up the loins of your mind, be sober, and hope to the end for the grace that is to be brought unto you at the revelation of Jesus Christ; As obedient children, not fashioning yourselves according to the former lusts in your ignorance: But as he which hath called you is holy, so be ye holy in all manner of conversation; Because it is written, Be ye holy; for I am holy. [Leviticus 11:44-45] And if ye call on the Father, who without respect of persons judgeth according to every man's work, pass the time of your sojourning here in fear: Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers; But with the precious blood of Christ, as of a lamb without blemish and without spot: Who verily was foreordained before the foundation of the world, but was manifest in these last times for you, Who by him do believe in God, that raised him up from the dead, and gave him glory; that your faith and hope might be in God. Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that ye love one another with a pure heart fervently: Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever. For all flesh is as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away: But the word of the Lord endureth for ever. And this is the word which by the gospel is preached unto you.
[AD 420] Jerome on Leviticus 11:44
“Be holy, says the Lord, for I am holy.” The apostles boasted that they had left all things and had followed the Savior. We do not read that they left anything except their ship and their nets; yet they were crowned with the approval of him who was to be their judge. Why? Because in offering up themselves they had indeed left all that they had.

[AD 461] Leo the Great on Leviticus 11:44
He himself says, “Be holy, for I am holy,” that is to say, choose me and keep away from what displeases me. Do what I love; love what I do. If what I order seems difficult, come back to me who ordered it, so that from where the command was given help might be offered. I who furnished the desire will not refuse support. Fast from contradiction, abstain from opposition. Let me be your food and drink. None desire in vain what is mine, for those who stretch out toward me seek me because I first sought them.

[AD 542] Caesarius of Arles on Leviticus 11:44
Pious souls of the Lord, what the Lord admonishes us is not to be considered merely in passing, for he says, “Be holy because I am holy.” Although this term properly belongs to all the Christian people, according to what blessed Peter says, “You, however, are a chosen race, a royal priesthood, a holy nation,” this term seems particularly to apply to all priests in a special way. In all the letters which are addressed to the Lord’s priests by any men whatsoever, it is specially indicated that they are holy. Since then this term is applied to us, we ought to inquire what precisely is its meaning. It is only through Greek that the interpretation of this word holy can be discovered. For agios is the Greek for “holy,” and agios has the meaning “not of the earth.” Therefore if we are more solicitous for heavenly things than for those of earth, this term is not unfittingly applied to us.
