Charles Ellicott Commentary 2 Chronicles 27:7

"Now the rest of the acts of Jotham, and all his wars, and his ways, behold, they are written in the book of the kings of Israel and Judah." — 2 Chronicles 27:7 (ASV)

And all his wars, and his ways. — See 2 Kings 15:36, And all that he did. The chronicler seems to have varied the phrase, in order to hint at the Syro-Ephraite war, mentioned in 2 Kings 15:37.
