Facing a military threat he cannot handle on his own, the king of Judah reaches out to the king of Aram for assistance. He bases this appeal on a long history of peaceful relations between their two kingdoms. Even though they never established a formal treaty, they have never engaged in any conflicts, partly because they do not share a common border [ביאור שטיינזלץ].
In his message, the king of Judah asks the Aramean leader to cancel his current alliance with Baasha, the king of Israel [מצודת ציון]. To persuade him to break this pact, he sends a bribe of financial wealth, urging the king of Aram to prioritize Judah's interests over those of Israel [ביאור שטיינזלץ].
The ultimate goal of this political maneuver is to force the king of Israel to withdraw. By convincing the king of Aram to launch a military attack against Israel from the north, the king of Judah hopes to create a severe distraction. This sudden provocation will leave the king of Israel with no choice but to retreat and stop his harassment of Judah [מצודת דוד, ביאור שטיינזלץ].
