John Gill Commentary 2 Chronicles 19:3

"Nevertheless there are good things found in thee, in that thou hast put away the Asheroth out of the land, and hast set thy heart to seek God." — 2 Chronicles 19:3 (ASV)

Nevertheless, there are good things found in thee
Principles of grace, righteousness, and holiness, faith, love, zeal, and other graces, true and genuine, from which sprung many good works done by him:

in that you have taken away the groves out of the land ;
cut down the groves of trees, and destroyed the idols and images in them:

and have prepared your heart to seek God ;
through the grace of God his heart was disposed to serve and worship the Lord, and to seek his honour and glory.
