A sudden discovery within the Temple triggers a profound panic, prompting an urgent appeal for divine guidance. After a Torah scroll is found, the king commands his messengers to seek out the prophets. He desperately needs them to ask God for direction on behalf of himself, the people present with him, and the entire nation of Judah [מצודת דוד, ביאור שטיינזלץ].
This intense alarm is directly tied to the contents of the newly discovered scroll. Upon opening the book, verses detailing severe disaster appeared right at the top of the page. This immediate exposure to words of doom is interpreted as a clear, undeniable sign that God is preparing to execute the harsh punishments recorded there [מצודת דוד].
Realizing the gravity of the situation, the king understands that God's great anger [ביאור שטיינזלץ] is aimed directly at the nation, a consequence of their ancestors failing to keep His word. The nature of this divine wrath is described as a force being poured out or emptied from above [מצודת ציון]. This imagery is highly deliberate. Because fierce anger is often compared to a blazing fire, it is fittingly described as a substance that melts. It acts like a liquid fire, melting and pouring down upon the sinners, burning with an intensity that cannot be put out [רש״י].
