שופטים, פרק א׳, פסוק ג׳

The effort to complete the conquest of the land sparks a strategic military alliance. Recognizing the need for mutual support against the remaining enemies in unconquered territories, a call for partnership is made. The primary approach among commentators is that this represents a national appeal from the tribe of Judah to the tribe of Simeon. However, an alternative perspective views this as a personal exchange between individuals. In this view, the speaker is Othniel son of Kenaz, also known as Jabez, who is referred to as Judah and is reaching out to his biological brother, Simeon [רש״י].

The choice to partner with Simeon over any other tribe is highly intentional. While it reflects a deep bond of love between them, it is primarily driven by practical geography. The land assigned to Simeon was actually an enclave situated entirely within the much larger territory of Judah [מלבי״ם, אברבנאל, ביאור שטיינזלץ]. Because they were such close neighbors, launching a joint military operation is a natural and logical step. The proposed agreement is a straightforward exchange: if Simeon helps conquer the territory assigned to Judah, Judah will return the favor and help secure Simeon's land [רש״י, אברבנאל, ביאור שטיינזלץ].

The nature of this military pact also reveals the physical landscape of the battlefield. The request for Simeon's help involves an invitation to ascend, while the promise to assist Simeon involves a simple commitment to travel. This shift in action is tied directly to the topography of their respective regions. Judah's territory is situated in a mountainous area that requires a physical climb to engage the enemy, whereas Simeon's territory lies in a flat plain where troops only need to march forward [מלבי״ם].
