מלכים ב, פרק י״ט, פסוק ל״ד

The promise of salvation for Jerusalem rests on a firm commitment from God to defend His people. He assures that He will actively guard the city, acting as a direct shield against harm [מצודת ציון, רלב״ג, ביאור שטיינזלץ]. This defense is not merely a boundary but a complete canopy of protection spread directly over Jerusalem to keep it safe [מנחת שי, ביאור שטיינזלץ].

This unwavering protection is driven by two central reasons. First, God defends the city for His own sake, acting specifically to uphold the honor of His name [מצודת דוד, רלב״ג]. Second, the salvation honors the historical covenant God established with David. Through this enduring promise, God ensured that the royal leadership would never depart from David's descendants, provided that they remain faithful and keep the commandments [רלב״ג].
