2 Chronicles 19:3

Then Samuel spoke to all the house of Israel, saying, “If you are to return to Yahweh with all your heart, then remove the foreign gods and the Ashtaroth from among you and set your hearts toward Yahweh and serve Him alone; and He will deliver you from the hand of the Philistines.”

“And all Israel shall mourn for him and bury him, for he alone of Jeroboam’s family will come to the grave, because in him something good was found toward Yahweh, the God of Israel, in the house of Jeroboam.

And when he humbled himself, the anger of Yahweh turned away from him, so as not to ruin him completely; and also conditions were good in Judah.

And he did evil because he did not set his heart to seek Yahweh.

And Jehoshaphat was afraid and set his face to seek Yahweh, and called for a fast throughout all Judah.

The high places, however, were not taken away; the people had not yet set their hearts to the God of their fathers.

for everyone who prepares his heart to seek God, Yahweh, the God of his fathers, though not according to the rules of cleansing of the sanctuary.”
