דברי הימים ב, פרק י״ג, פסוק י״ח

The outcome of the battle between the two kingdoms was determined by faith and trust rather than military advantage. While the Israelites were subdued, the people of Judah prevailed and grew strong [ביאור שטיינזלץ]. This shift in power did not stem from physical might or the size of their army. Instead, the people of Judah found the inner strength to win the battle solely because of their absolute reliance on God [מלבי״ם].
