John Gill's  Exposition of the Bible 

2 Kings 13:8

Now the rest of the acts of Jehoahaz, and all that he did, and his might, are they not written in the book of the chronicles of the kings of Israel?

Now the rest of the acts of Jehoahaz, and all that he did, and his might,.... Which he exerted against the Syrians, being a man of courage, though not successful, because the Lord was not with him, but against him:

are they not written in the book of the chronicles of the kings of Israel? where their acts, and the events of their reigns, were recorded.
