Note verse 20
2 Chronicles 32:20
King Hezekiah and the prophet Isaiah son of Amoz cried out in prayer to heaven about this.
We have the prayer in both Isaiah and 2 Kings.
Hezekiah prayed. Isaiah gave a prophecy, promising what would happen and we read the rest in 2 Chronicles:
That’s not something Sennacherib would write home about. God turned it around in the middle of the night, in the height of the crisis. It is just as impressive as a path through the sea.
Hezekiah faced an impossible situation and he and Isaiah cried out in prayer.
