John Gill's Bible Commentary Ver. 6. And the rest of the acts of Azariah, and all that he did, are they not written in the book of the chronicles of the kings of Judah ?] In the history of the reigns of those kings; some of them are recorded in the canonical book of the Chronicles, ( 2 Chronicles 26:1-23) and some were written by the prophet Isaiah, ( 2 Chronicles 26:22).
Matthew Henry Commentary
Verses 1-7 - Uzziah did for the most part that which was right. It was happy for the kingdom that a good reign was a long one.
