2 Chronicles 19 verse 3

And when he humbled himself, the wrath of the LORD turned from him, that he would not destroy him altogether: and also in Judah things went well.

And the LORD was with Jehoshaphat, because he walked in the first ways of his father David, and sought not unto Baalim; But sought to the LORD God of his father, and walked in his commandments, and not after the doings of Israel. Therefore the LORD stablished the kingdom in his hand; and all Judah brought to Jehoshaphat presents; and he had riches and honour in abundance. And his heart was lifted up in the ways of the LORD: moreover he took away the high places and groves out of Judah.

And all Israel shall mourn for him, and bury him: for he only of Jeroboam shall come to the grave, because in him there is found some good thing toward the LORD God of Israel in the house of Jeroboam.

For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.

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.

For Ezra had prepared his heart to seek the law of the LORD, and to do it, and to teach in Israel statutes and judgments.

My heart is fixed, O God, my heart is fixed: I will sing and give praise.
