2 Chronicles 12:14
And he did evil, because he prepared not his heart to seek the LORD.
And he did evil,.... Committed idolatry, relapsed into that, his humiliation not being hearty and sincere:
because he prepared not his heart to seek the LORD; by prayer and supplication, and by an attendance on the service and worship of God; for though he did these things outwardly, yet not sincerely and heartily; he did not engage in them seriously and in good earnest, with affection and fervour.
