John Gill Commentary 2 Kings 16:19

"Now the rest of the acts of Ahaz which he did, are they not written in the book of the chronicles of the kings of Judah?" — 2 Kings 16:19 (ASV)

Now the rest of the acts of Ahaz which he did, are they not
written in the book of the chronicles of the kings of Judah ?
] Some others are written in the canonical book of Chronicles, (2 Chronicles 28:1) and were, it is highly probable, in the annals of the kings of Judah, now lost.
