2 Chronicles 32:31-32

However, when ambassadors arrived from Babylon to ask about the remarkable events that had taken place in the land, God withdrew from Hezekiah in order to test him and to see what was really in his heart. The rest of the events in Hezekiah’s reign and his acts of devotion are recorded in The Vision of the Prophet Isaiah Son of Amoz, which is included in The Book of the Kings of Judah and Israel.
