Charles Ellicott Commentary 2 Kings 14:15-16

"Now the rest of the acts of Jehoash which he did, and his might, and how he fought with Amaziah king of Judah, are they not written in the book of the chronicles of the kings of Israel? And Jehoash slept with his fathers, and was buried in Samaria with the kings of Israel; and Jeroboam his son reigned in his stead." — 2 Kings 14:15-16 (ASV)

Now the rest ... — Compare 2 Kings 13:12–13, where the reign of Jehoash is already summed up, though not entirely in the same phraseology. The compiler probably found 2 Kings 14:15–16 in their present position in the document from which he derived the entire section, 2 Kings 14:8–17. This document was not the same as that upon which 2 Kings 13 depends, as appears from the differences in language in the two passages.

The two verses are almost necessary here as a suitable introduction to the statement in 2 Kings 14:17, that Amaziah survived Jehoash by fifteen years.
