Parashat Korach: The Covenant of Salt
What Is the Connection Between Korach’s Rebellion and the Covenant of Salt?
What is the Connection Between Salt and the Service of the Kohanim?
As a child I used to have a sweet tooth but I’m gradually developing a more ‘salty tooth!’ Whereas the importance of reducing salt intake is well known for cardiovascular health and preventing kidney disease, only later in life did I learn about the benefits of adding good unrefined sea salt to my diet and to the water I drink in the morning.
Salt is essential for life. Over time, I learned to add a small amount of unrefined salt to my water bottle to help replenish electrolytes and support hydration. I usually use Himalayan Crystal Salt, which many health-conscious people value for its trace minerals, including potassium, calcium, and magnesium. Salt also enriches food by releasing aromatic compounds and enhancing flavor. In fermentation, it helps inhibit harmful spoilage bacteria while allowing beneficial lactic acid bacteria to thrive, as in kimchi, pickles, and sauerkraut. What especially fascinates me is salt’s ability to bring out the flavor of other foods. Even a pinch in a cookie can heighten its sweetness. Before refrigeration, salting was one of the main ways to keep food from spoiling.
Today salt is still central in the Torah-observant home as it must always be on the table. Our table symbolizes the altar on which sacrifices were offered, and no sacrifice was brought without salt, as it states: “You shall salt every one of your meal offering sacrifices with salt, and you shall not omit the salt of your G-d’s covenant from upon your meal offerings. You shall offer salt on all your sacrifices” (Vayikra 2:13). Moreover, when breaking bread, we sprinkle salt on the slices before passing them to the people seated around the table.
I would like to explore the significance of salt and its intrinsic connection with the sacrifices. Why does the Torah require salt on every offering? Why did Hashem choose salt as the symbol of His eternal covenant with Aharon and his descendants? And why are both the Kehunah and the Davidic monarchy described as a “covenant of salt”?
Why is Hashem’s Covenant with the Kohanim Called a Covenant of Salt?
After Korach’s rebellion was put down and Aharon’s ministry as the Kohen Gadol was vindicated, the Torah unexpectedly turns to the gifts of the Kohanim and concludes with an unusual declaration:
ספר במדבר פרק יח פסוק יט כָּל תְּרוּמֹת הַקֳּדָשִׁים אֲשֶׁר יָרִימוּ בְנֵי יִשְׂרָאֵל לַהַשֵּׁם נָתַתִּי לְךָ וּלְבָנֶיךָ וְלִבְנֹתֶיךָ אִתְּךָ לְחָק עוֹלָם בְּרִית מֶלַח עוֹלָם הִוא לִפְנֵי הַשֵּׁם לְךָ וּלְזַרְעֲךָ אִתָּךְ:
“All the sacred gifts that the Children of Israel raise up to Hashem I have given to you, your sons, and your daughters with you as an eternal statute. It is an eternal covenant of salt before Hashem for you and your descendants with you” (Bamidbar 18:19).
Rashi explains that Hashem sealed His covenant with Aharon through salt, a healthy substance that endures and preserves everything it touches. Just as salt does not spoil, the covenant of Kehunah (priesthood) will never end (Rashi, Bamidbar 18:19). Drawing on the Sifri, he adds that the covenant was made through something not only resistant to decay, but also able to preserve and strengthen others (Sifri Bamidbar, Korach 118). The Rashbam similarly explains that a covenant of salt symbolizes permanence and continuity throughout the generations (Rashbam, Bamidbar 18:19).
This symbolism extends beyond the Kehunah. The Ben Ish Chai notes that there was a custom among the Jews of Baghdad to put salt on the dish that they used to gather pieces of bread while searching for chametz before Pesach. One of the reasons he suggests for this tradition is that salt serves as an omen that this mitzvah will be fulfilled for many years to come, as the Torah refers to salt as an “eternal covenant” (Halachot, Year 1, Tzav, 6).
Scripture also describes the Davidic monarchy as a covenant of salt: “Surely you know that the Eternal G-d of Israel gave David kingship over Israel forever, to him and his sons, by a covenant of salt” (II Divrei HaYamim 13:5). Kingdoms rise and fall, empires disappear, and political systems change. Yet Hashem’s covenant with Aharon and His covenant with David endure. Salt therefore becomes a symbol not merely of nourishment, but of lasting nourishment.
How Can Salt Both Preserve and Destroy?
Rabbeinu Bachaya offers a remarkable insight into the deeper symbolism of salt. On the one hand, salt preserves food and protects it from decay. On the other hand, salt can render land barren, preventing anything from growing. As the prophet states, “a salt land that remains uninhabited” (Yirmiyahu 17:6). Salt therefore embodies two opposite qualities simultaneously.
How can one substance both preserve life and inhibit growth? Rabbeinu Bachaya explains that salt originates from water yet is formed through the heat of the sun. Salt therefore contains within itself the powers of both water and fire. These correspond to the two Divine attributes through which the world is sustained: Compassion (Midat HaRachamim) and Justice (Midat HaDin). Just as salt unites opposite forces within a single substance, the world itself endures only through the balance of compassion and judgment.
This idea is illustrated by a striking Midrash. A king wished to fill delicate glass cups. If he poured only hot water into them, they would shatter. If he poured only cold water into them, they would crack. Therefore, he mixed the hot and cold water together, and the cups endured. Likewise, Hashem said: “If I create the world solely with the attribute of mercy, sin will abound. If I create it solely with the attribute of justice, how can the world endure? Rather, I will create it with both the attribute of justice and the attribute of mercy” (Midrash Bereishit Rabbah 12:15; Rabbeinu Bachaya, Vayikra 2:13).
For this reason, salt is called in the Torah “the salt of the covenant of your G-d.” It becomes a symbol of the Divine covenant itself. It both preserves and destroys, sustains and restrains. A place saturated with salt may become barren yet salt also preserves food and gives flavor to every meal. What appear to be opposite powers are, in truth, expressions of a single Divine wisdom. Perhaps this explains why every offering upon the altar requires salt. The covenant between Hashem and Israel is sustained through the delicate balance of kindness and restraint, abundance and discipline, mercy and judgment. Lasting nourishment emerges when these forces work together in harmony.
Why Is Salt Called the Sustaining Force of the World?
Rabbeinu Bachaya notes an additional lesson hidden in the Torah’s command, “With salt you shall salt” (Vayikra 2:13). The salt must not be so weak that it dissolves immediately, nor so strong that it draws out all the moisture and life from the meat. Even salt itself requires balance. Too little accomplishes nothing, while too much destroys. Nourishment depends not upon excess but upon harmony.
Rabbeinu Bachaya goes even further, describing salt as “the salt of the world” because it sustains existence itself. Rabbi Moshe Teitelbaum expands upon this idea. Every living creature is made of flesh, and flesh naturally tends toward decay. Yet Hashem established a covenant that living flesh should not immediately spoil. This ongoing preservation is itself the “salt” that sustains the world (Yismach Moshe, Parashat Korach).
We often imagine that food sustains life. Yet when we look deeper, we may discover that its continued existence is ultimately a gift of G-d. Just as a lifeless body naturally decays, food itself quickly spoils. Salt becomes a symbol of the hidden Divine force that continually preserves life and nourishment from moment to moment.
What is the Salt that Preserves Our Spiritual Nourishment?
This symbolism of salt can be applied to the role of the tzaddik. Just as salt prevents meat from spoiling, the tzaddik prevents the world from deteriorating spiritually. Through his pure thoughts and righteous actions, he weakens destructive desires and preserves the spiritual health of society (Degel Machaneh Ephraim, Parashat Korach).
This idea offers a new perspective on the covenant of Kehunah. The Kohanim were given gifts not as a privilege, but as part of a sacred duty: to preserve and elevate the nation’s spiritual life. Like salt, which is often unnoticed despite its importance, Israel’s true spiritual leaders sustain the nation in quiet, hidden ways. Moreover, salt enhances and preserves, teaching us that its spiritual quality is one of humility and service to others. Thus, salt has a natural affinity with the service of the Kohanim, whose role was to serve the people by offering their sacrifices and to serve Hashem through the Temple service.
Yet what enables a person to become a holy preserving force in the world? Good deeds performed without humility are like food without salt. Just as salt preserves food, humility preserves spiritual accomplishments. Without humility, even the most impressive acts of service eventually spoil (Ahavat Shalom, Parashat Eikev).
This teaching strikes at the very heart of Korach’s rebellion. Korach possessed greatness, wisdom, and spiritual stature. Yet he lacked the humility necessary to preserve those gifts. Aharon, by contrast, embodied humility. He understood that everything he possessed came from Hashem. Even the greatest tzaddik cannot claim ownership over his achievements. Everything we receive – physical nourishment, spiritual insight, wisdom, and success – is a gift bestowed by Divine kindness (Ma’or VaShemesh, Parashat Korach).
Perhaps this is the deepest lesson of the covenant of salt. Nourishment is not merely about receiving blessings but about preserving them. Just as a small amount of salt can preserve an entire meal, genuine humility can preserve a lifetime of spiritual accomplishments.
