Following the great rescue from Sennacherib, a profound era of peace and absolute security descends upon Hezekiah and the people of Jerusalem. This divine salvation extends far beyond the immediate Assyrian threat. God protects the nation from all their other enemies, providing them with a comprehensive shield of safety [ביאור שטיינזלץ].
The primary approach among commentators is that God now guides the people with deep compassion, gentleness, and rest. This specific type of tender care is uniquely suited for a nation that has been left entirely helpless, lacking the strength to carry on by themselves [מלבי ם]. Enveloped by this gentle guidance, the people are led into a state of total tranquility. God directs them peacefully throughout their entire region, ensuring they can live completely free from the fear of the many threats that once surrounded them [חומת אנך].
