In the midst of a severe rebellion threatening the leadership of the nation, the conflict splits into two distinct fronts. While Korah and his followers challenge the priesthood, Dathan and Abiram focus on a political opposition, protesting Moses' leadership and the denial of the firstborn rights from the tribe of Reuben [רש״ר הירש, מלבי״ם, קונטרס חיבה יתירה]. Faced with this crisis, Moses chooses not to rely on a public rebuke, but instead seeks a path of personal dialogue. He approaches Korah first, as Korah is the primary leader of the uprising and is located nearby in the Levite camp. Dathan and Abiram, on the other hand, have distanced themselves, retreating to their own tents [רמב״ן, טור הארוך, צאינה וראינה]. The decision to send for Dathan and Abiram reveals Moses' immense humility and his deep desire to prevent a permanent tear within the nation. Despite his elevated status as a king and prophet, he initiates contact with two common citizens, hoping to soften their hearts through a private conversation away from the angry, incited crowd [אור החיים].
From this action, a major moral principle emerges regarding the danger of holding onto a dispute. Moses teaches that even when a person is clearly in the right, it is proper to pursue those who argue and attempt to reconcile with them peacefully [רש״י, חתם סופר]. On a legal level, this event serves as the foundation for the rule that when a court summons an individual, it must do so specifically through an appointed messenger [תורה תמימה]. Noticeably absent from this summons is On ben Peleth, who was previously mentioned as a partner in the rebellion. His absence suggests that he is merely a secondary figure following the advice of Dathan and Abiram. Alternatively, he may have already backed away from the dispute, saving himself from death thanks to the wise counsel of his wife [רמב״ן, טור הארוך, צאינה וראינה].
When Dathan and Abiram insolently refuse the summons, their rejection of ascending carries several layers of meaning. In a practical sense, traveling to a judge, visiting a chosen place, or serving God is traditionally described as an ascent, and it is also possible that the Tabernacle was physically located on higher ground [רשב״ם, רבנו בחיי, אבן עזרא, חזקוני, העמק דבר]. By refusing to ascend, they completely reject Moses' authority to judge or command them [רש״ר הירש, ביאור שטיינזלץ, בכור שור]. Beyond their rejection of his authority, Dathan and Abiram suspect that Moses is inviting them over to offer a political bribe, such as a position of power, land, or a promotion, in exchange for abandoning the rebellion and calming the people. Their refusal is designed to show their total disgust for any offer of elevation or status from him [כלי יקר, אור החיים, מלבי״ם].
The rebels also employ biting irony, sarcastically claiming that Moses has already brought them up from a land flowing with milk and honey, a term they twist to describe the impurity of Egypt, only to kill them in the desert. Therefore, they reject any further elevation from him [אור החיים, ברכת אשר]. Beneath their conscious defiance lies a tragic irony. By firmly declaring that they will not ascend, they unknowingly seal their own fate. Their words become a self-fulfilling prophecy, as from that moment forward, the only path left for them is a descent into the belly of the earth and toward death [רש״י, צאינה וראינה].
