The controversy Korach initiated against Moshe Rabbeinu serves as the paradigm of a machlokes shelo l’shem Shomayim – a dispute that is not for the sake of Heaven. Korach rebelled against Moshe Rabbeinu and, by extension, against Hashem and His Torah. Chazal teach that such a dispute is destined not to endure, for it is rooted, not in truth, but in ego and self-interest.
What is a machlokes? The word is rooted in chelek – a portion, a division. A baal machlokes is one who separates himself from others, creating fragmentation where there should be unity. He does not merely disagree; he divides. Where once there had been connection, distance has replaced the connection. Each individual stands alone, no longer part of a greater whole.
Yet, perhaps there is a deeper, more subtle meaning embedded in this word, machlokes, which allows us a window into this and all controversy. The term chalak (same letters) also means smooth. (Yaakov Avinu was chalak, as opposed to Eisav, who was hairy.) How does this shed light on the anatomy of discord?
Every genuine relationship is formed by two individuals, each possessing unique strengths and weaknesses, talents and deficiencies, perspectives and dispositions. No two people are identical – and it is precisely this lack of uniformity that allows for connection. Like two uneven surfaces, their differences interlock. The strength of one compensates for the other’s weakness; one’s insight enhances the other’s limitation. Together, they form something whole, something enduring. Indeed, it is the “rough edges,” the subtle irregularities, that allow for bonding. Much like porous material that absorbs and holds adhesive, a person who recognizes his own incompleteness creates space for another to enter. He has room to give, and the other has room to receive.
In contrast, two perfectly smooth surfaces cannot adhere to one another. They may appear refined, polished, even flawless – but they cannot connect. They have nothing to hold them together. No depth. No receptivity. The very smoothness becomes the obstacle to unity.
So, too, in human relationships. When one engages in machlokes, he “smooths” himself out in relation to the other. He no longer sees himself as part of a shared structure, but rather, he is a self-contained entity. His perspective is complete; his position is unassailable. He has no room for another voice, no tolerance for difference. In his mind, he is lacking nothing– and, therefore, he has no need for anyone else.
This was the tragic error of Korach. He cloaked his rebellion in the language of equality – Ki chol ha’eidah kulam kedoshim. Yet, beneath the rhetoric, lay a refusal to accept his role, his chelek, within Klal Yisrael. He did not seek to contribute; he sought to replace. He did not wish to complement Moshe Rabbeinu; he wished to stand apart from him. In doing so, he transformed potential harmony into destructive division.
A machlokes l’shem Shomayim, such as that of Hillel and Shammai, is fundamentally different. In a machlokes l’shem Shomayim, each side recognizes its own incompleteness. Each view is a chelek, a part of a greater truth. The disagreement itself becomes a vehicle for growth, for clarity, for a deeper revelation of Torah. Because each side remains “porous,” open and receptive, the relationship endures – even thrives – despite the differences, sometimes even as a result of the differences.
We now understand that the danger of machlokes is not only in the disagreement itself, but also in what it reveals about the individual. When a person becomes “smooth,” when he allows no room for others, he renders connection impossible. When one embraces his own limitations, however, when he recognizes that he is but a chelek, he becomes capable of true unity.
Relationships between husband and wife, siblings, members of a community, are not built upon uniformity, but upon complementary differences. Everyone has some sort of flaw/deficiency which the other party/spouse/friend complements, thus making the two “whole.” It is not the absence of flaws that creates strength, but the ability to work with them and integrate them into a relationship. When humility exists (on both sides); when respect for one another reigns, the relationship has texture. Where there is texture, it is possibile for connection. When two people connect on such a level, where each one balances the other, they have hope for enduring peace. Korach’s controversy is paradigmatic in the sense that this type of fissure, a desire to be self-sufficient and “smooth,” is the root of the poison characteristic of some machlokes.
