דברי הימים ב, פרק ל׳, פסוק כ׳

When a leader steps forward to intercede for a nation that has faltered, the ultimate hope is for divine mercy and restoration. In this instance, the king's prayer is met with complete favor in heaven. God listens to Hezekiah, signaling His agreement with the leader and confirming that everything proceeded exactly as it should [ביאור שטיינזלץ]. Furthermore, the acceptance of this prayer serves as clear proof that the sacrifices offered by the people were fully desired and welcomed by God [חומת אנך].

As a result of this divine favor, God brings healing to the nation. The commentators agree that this does not refer to a physical cure, but rather to a profound spiritual recovery. Sin is viewed as an illness of the soul, making atonement the necessary cure [מצודת ציון]. This concept of equating the pardon of sins with healing is a familiar biblical theme, echoing the plea found in Psalms to heal the soul that has sinned [רד״ק, מצודת ציון]. Ultimately, in response to the king's sincere plea, God grants the people full forgiveness and completely atones for their wrongdoings [מצודת דוד, רד״ק, ביאור שטיינזלץ].
