Two of the "clean animal" markers in Leviticus are chewing the cud and having a split hoof. It's easy to read those as if they were a line drawn somewhere, for reasons lost to us. But when you sit with them a little, it starts to feel more intentional, and many have considered this. These likely are not simply arbitrary food rules, and likely carry a larger message or teaching. Jesus Himself declared that it is not what goes in that makes one unclean, but rather what comes out. Suggesting there is a larger understanding to be had here than simply physical diets and consumption through the stomach. I want to hold that loosely, and just keep it in thought for now.
What the Letter of Aristeas and Philo Say About Chewing the Cud
This isn't a new thought I am presenting here, and it's worth saying so before going any further with it. The Letter of Aristeas, a Hellenistic Jewish text from around the 2nd century BC, already reads the cud-chewing animal as a symbol of memory, describing the act of chewing as nothing more than recalling one's own life and origin, God's hand in creation. The same text describes the split hoof as a symbol of discernment: the capacity to separate right from wrong.
Philo of Alexandria has the same starting point, too. In On the Special Laws, he walks through the actual mechanics of rumination, and how the animal draws its food down, softens it slowly, sends it back down again. He maps that directly onto how a person receives instruction. A student takes in a teaching by ear, but can't hold it firmly all at once. It has to be worked over, again and again, by "the continued exercise of his memory," before it's actually fixed in the soul. Both writers land on the same word, memory, but Philo turns it into something closer to a working model of learning: receive, soften, rework, internalize. Personally, I find this method of looking at it more trustworthy, as we can objectively understand mechanics.
None of this, regardless of who, should be taken as more certain than it is. Aristeas is an example (though the same applies to any human being), because in the same writing, he also draws meaning through the idea that weasels had a meaning being their conception. In a time where it was believed hey conceive through the ear and give birth through the mouth. A biological claim that simply isn't true. He was reasoning from the natural world as he, and many in his culture, understood it, and like anyone's, was imperfect and partial. That doesn't disqualify the instinct to look for meaning in the created order, not conclusions he attached to. It just means the specific readings he and Philo arrived at are themselves someone's best attempt, not the final word, which is worth remembering before treating any reading here, including my own, as more settled than it is. We know things only in part.
What a Split Hoof Symbolizes: Stability Over Rough Terrain?
The traditional reading ties the split hoof to discernment itself, the ability to divide one thing from another. I'm drawn to something near to that, but not identical, which is: stability over terrain. A cloven hoof splits an animal's weight across two hooves instead of one solid mass, which lets the foot flex and grip on uneven and rocky ground as to not roll or slip.
Solid Hoofed: Built for speed and hard, open ground. A single solid point of contact allows for powerful strides and efficient running on flat terrain.
Split Hoofed: Built for stability and varied terrain. The two toes can spread apart to grip soft mud, steep hills, or rocky ground, absorbing shock and distributing weight evenly.
It's a foot built for footing that's been tested, literally, over rough terrain, over time. So where Aristeas and Philo read the hoof as the capacity to discern, I find myself reading it as something like the result of discernment repeated long enough to hold. What's been walked on, tested through rough terrain, and still stands. This might even be the crux of their point already, since good discernment practiced consistently is probably a large part of what produces that kind of stability in the first place.
The Biology Behind Clean and Unclean Animals
To chew the cud is to take something in and keep working it. To not chew the cud is to take it in and leave it as it arrived. A cleft hoof holds on uneven ground: flexible, able to grip what shifts. A solid hoof only holds where the ground already agrees with it.
Two animals break this pairing, in opposite directions: the camel and the pig.
Why Is the Pig Unclean If It Has a Split Hoof?
The pig has the foot built for rough ground, but never does the reprocessing. It has the capacity to hold what shifts, without ever putting anything it takes in through that process. The shape of trustworthiness, without the history that would earn it.
Why Is the Camel Unclean If It Chews the Cud?
The camel does the reprocessing endlessly, but never gets the foot built to hold what's uneven. Tested and re-tested internally, never actually held up against real terrain. Something worked over completely in the mind, never checked against reality.
It's worth mentioning though, toed animals have "stability." And the camel chews cud, but does have split toes. So why discriminate this against split hooves, if stability is all that matters? The reality is, I don't think it's only "stability" either. I think this meaning goes deeper, but to a depth I may need to make another article for. Perhaps I need to chew it over more.
However, I don't think we need the ultimate meaning, to gain an important understanding. Both animals end up unclean, from opposite directions. Using the symbolic sense, one stands on ground it's never earned, the other has a rumination it's never tested. I think whatever deeper meaning there is to be found, will only be complementary to the crux of this duality. We ought to look at things, based on immediate and long-term traits. And through this, we need to discern to what purpose it has had over time, what shaped it, and what fruit has it rightly born?
A final consideration when searching around this topic was "Every foot tells you where the animal lives" facebook post I came across. Where it mentions "Feet reveal an enormous amount about how an animal moves and where it spends its life." And personally, I find that an interesting nature to God's creation. Often I like to look at the realities of His creation. Scripture tells us the world around us speaks to God's Word. When looking for meaning, why not look at God's literal creation, the works of His very hand? And though many treat science as an opposition to religion, could science be just one tool on the belt of understanding God?
A Caution: Where Symbolic Readings of Law Go Too Far
It's worth naming a real problem point here, because it can start from exactly the method being used in this post. The Epistle of Barnabas, an early Christian text, reads these same laws symbolically. Cud-chewing as meditating on the word, the cloven hoof as discernment, and then goes further, claiming the literal dietary law was never actually about food at all. That Israel simply misunderstood Moses, and the real commandment was always spiritual, with the physical law just a costume for it.
That's the line I don't want to cross, and I don't think anyone should hastily. In fact, that kind of extreme reframing with revisionist doubt, sounds awfully familiar, doesn't it? E.g., "Did God really say to not eat the fruit? Perhaps He said that for other reasons..."
I believe this law really was about food, and intended to actually change dietary habits of Israelites, for likely multiple reasons. Noticing a pattern of meaning inside or additionally to it doesn't undo that. The safer shape is "this real law about real food also carries something meant for the journey afterwards," not "this was never really about food at all."
Only God, and those whom He reveals it to, know these things.
I tend to view God as a mysteriously efficient creator, in ways humans may mistake is inefficient because they are unable to see the larger picture. Meaning, when He does something, it is to serve both a current purpose and a future purpose. Humans, looking back on this, often either cling to the then-current purpose, or disregard the lesson of the old purpose and adopt the new one entirely. I think Jesus said something that shines light on this in Matthew 13, on the scribe who brings out of his treasure what is new and old.
Hold Loosely, Still
Chewing the cud as reprocessing what's been received, the cloven hoof as something like tested stability, though I'll admit that reading isn't finished. The camel's own split toes are proof of that. I don't think it unravels the idea so much as it points past it, toward whatever actually separates the two: not stability by itself, but discernment sustained long enough to produce it, and the fruit that comes from staying with something rather than settling for how it looks on the surface. That's likely a piece for another time.
What I keep coming back to is Jesus' own line: it isn't what goes in that defiles a person, but what comes out. If this pattern points anywhere, it's probably there. Not the food itself, but what's done with what's taken in. Worked over, tested, allowed to bear fruit over time, rather than swallowed whole and left exactly as it arrived.
I'd rather leave it there than force a clean and neat conclusion for its own sake. If you see it differently, or think you see the piece I'm missing, I'd genuinely like to hear it.
