Albert Barnes Commentary 2 Kings 14:3

"And he did that which was right in the eyes of Jehovah, yet not like David his father: he did according to all that Joash his father had done." — 2 Kings 14:3 (ASV)

He did ... as Joash - There is a curious parallel between the lives of Joash and Amaziah. Both were zealous for Yahweh in the earlier portion of their reigns, but in the latter part fell away; both disregarded the rebukes of prophets; and both, having forsaken God, were in the end conspired against and slain (Compare to 2 Chronicles 24:25; 2 Chronicles 25:27).
