John Gill Commentary 2 Kings 22:2

"And he did that which was right in the eyes of Jehovah, and walked in all the way of David his father, and turned not aside to the right hand or to the left." — 2 Kings 22:2 (ASV)

And he did that which was right in the sight of the Lord
In the affair of religious worship especially, as well as in other things:

and walked in all the ways of David his father ;
in his religious ways, in which he never departed from his God:

and turned not aside to the right hand or to the left ;
but kept an even, constant, path of worship and duty, according to the law of God.
