2 Kings 14:3
And he did that which was right in the sight of the LORD, yet not like David his father: he did according to all things as Joash his father did. And he did that which was right in the sight of the LORD, yet not like David his father: he did according to all things as Joash his father did.
The verse belongs to the history of Judah's kings in a time of spotted record, when the nation prospered under righteous and faithful rulers, yet those rulers often later turned from God to idolatry and thereby brought calamity upon themselves and their people. In its wording both the distant ancestor David and the immediate father Joash are called father, showing that family terms can denote persons in different generations. Amaziah began his reign doing what was right before the Lord, yet not after the pattern of David, but according to all that Joash his father had done.
He stood above the average of Judah's kings, though he was not reckoned among the one truly good king, Jehoshaphat. His doing of what was right left reformation incomplete, for the high places were not taken away and the people still sacrificed and burned incense on them, so that right doing under a reformer could coexist with continued false worship when its places and practices were left standing. This incomplete removal parallels leaving the Sabbath of the Lord for Baal and then for Sunday, in that reformers arose both in Israel and in the Christian church, yet Sunday keeping remains to this day. His was a reign that began well but ended wickedly.
