2 Chronicles 32:31-32

Howbeit in the business of the ambassadors of the princes of Babylon, who sent unto him to enquire of the wonder that was done in the land, God left him, to try him, that he might know all that was in his heart. Now the rest of the acts of Hezekiah, and his goodness, behold, they are written in the vision of Isaiah the prophet, the son of Amoz, and in the book of the kings of Judah and Israel.
