2 Kings 14:3

And he did that which was right in the sight of the Lord
. At least externally, and at the beginning of his reign:

yet not like David his father;
not with a perfect heart, with that sincerity and uprightness as he did, see ( 2 Chronicles 25:2 ) ,

he did according to all things as Joash his father did;
who at first reigned well, and then fell into idolatry, as this his son did.
