2 Chronicles

And his heart was lifted up in the ways of the Lord: moreover he took away the high places and groves out of Judah.

Nevertheless there are good things found in thee, in that thou hast taken away the groves out of the land, and hast prepared thine heart to seek God.

And he did evil, because he prepared not his heart to seek the Lord.

That prepareth his heart to seek God, the Lord God of his fathers, though he be not cleansed according to the purification of the sanctuary.

And Samuel spake unto all the house of Israel, saying, If ye do return unto the Lord with all your hearts, then put away the strange gods and Ashtaroth from among you, and prepare your hearts unto the Lord, and serve him only: and he will deliver you out of the hand of the Philistines.
