Charles Ellicott Commentary 2 Chronicles 28:25

"And in every city of Judah he made high places to burn incense unto other gods, and provoked to anger Jehovah, the God of his fathers." — 2 Chronicles 28:25 (ASV)

And in every several city of Judah he made high places. — Compare 2 Chronicles 28:2–4.

And provoked to anger. —Deuteronomy 32:16. Instead of this, 2 Chronicles 28:18 obscurely mentions further changes which Ahaz made in the Temple, “for fear of the king of Assyria." It seems probable that the sacrilege described in 2 Chronicles 28:24 and in 2 Kings 16:17–18 was perpetrated in collecting everything of any value to send to the rapacious Assyrian.
