דברי הימים א, פרק י״ח, פסוק ה׳

A strong bond and formal alliance united the various Aramean kingdoms. Because of this deep connection, military conflicts involving one nation quickly drew in its allies. When Hadadezer, the king of Zobah, faced a severe military threat, the neighboring army of Aram Damascus mobilized and rushed to his defense.

This decision to intervene ultimately led to their downfall. David engaged the incoming forces of Aram Damascus and decisively struck them down, resulting in the deaths of twenty-two thousand Aramean soldiers [ביאור שטיינזלץ].
