2 Chronicles 32:31-32

And so in the matter of the envoys of the princes of Babylon, who had been sent to him to inquire about the sign that had been done in the land, God left him to himself, in order to test him and to know all that was in his heart. Now the rest of the acts of Hezekiah and his good deeds, 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.
