2 Chronicles 32:31-32

And so in the matter of the envoys of the rulers of Babylon, who were sent to him to inquire about the wonder that had happened in the land, God left him alone only to test him, in order to know everything that was in his heart. [Is 39:1-7] Now the rest of the acts of Hezekiah and his godly achievements, behold, they are written in the vision of Isaiah the prophet, the son of Amoz, in the Book of the Kings of Judah and Israel.
