He prepared not his heart ... - See the margin. Rehoboam's sin was want of earnestness and consistency.

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.

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

12:14 Did evil - Or, settled not, although he humbled himself, for a season, yet he quickly relapsed into sin, because his heart was not right with God.

prepared: or, fixed

12:1-16 Rehoboam, forsaking the Lord, is punished. - When Rehoboam was so strong that he supposed he had nothing to fear from Jeroboam, he cast off his outward profession of godliness. It is very common, but very lamentable, that men, who in distress or danger, or near death, seem much engaged in seeking and serving God, throw aside all their religion when they have received a merciful deliverance. God quickly brought troubles upon Judah, to awaken the people to repentance, before their hearts were hardened. Thus it becomes us, when we are under the rebukes of Providence, to justify God, and to judge ourselves. If we have humbled hearts under humbling providences, the affliction has done its work; it shall be removed, or the property of it be altered. The more God's service is compared with other services, the more reasonable and easy it will appear. Are the laws of temperance thought hard? The effects of intemperance will be found much harder. The service of God is perfect liberty; the service of our lusts is complete slavery. Rehoboam was never rightly fixed in his religion. He never quite cast off God; yet he engaged not his heart to seek the Lord. See what his fault was; he did not serve the Lord, because he did not seek the Lord. He did not pray, as Solomon, for wisdom and grace; he did not consult the word of God, did not seek to that as his oracle, nor follow its directions. He made nothing of his religion, because he did not set his heart to it, nor ever came up to a steady resolution in it. He did evil, because he never was determined for good.
