And at that time Hanani the seer came to Asa king of Judah, and said unto him, Because thou hast relied on the king of Syria, and not relied on the LORD thy God, therefore is the host of the king of Syria escaped out of thine hand.

Wesley's Notes

16:7 Escaped - And so reserved to be a scourge to thy kingdom and posterity: whereas if he had joined with Baasha against thee, thou shouldst have overthrown them both, and prevented all that mischief which that monarch will do to thy family.

Jamieson-Fausset-Brown Bible Commentary

7-10. Hanani the seer came to Asa . and said-His object was to show the king his error in forming his recent league with Ben-hadad. The prophet represented the appropriation of the temple treasures to purchase the services of the Syrian mercenaries, as indicating a distrust in God most blameable with the king's experience. He added, that in consequence of this want of faith, Asa had lost the opportunity of gaining a victory over the united forces of Baasha and Ben-hadad, more splendid than that obtained over the Ethiopians. Such a victory, by destroying their armies, would have deprived them of all power to molest him in the future; whereas by his foolish and worldly policy, so unworthy of God's vicegerent, to misapply the temple treasures and corrupt the fidelity of an ally of the king of Israel, he had tempted the cupidity of the one, and increased the hostility of the other, and rendered himself liable to renewed troubles (1Ki 15:32). This rebuke was pungent and, from its truth and justness, ought to have penetrated and afflicted the heart of such a man as Asa. But his pride was offended at the freedom taken by the honest reprover of royalty, and in a burst of passionate resentment, he ordered Hanani to be thrown into prison.

Matthew Henry's Concise Commentary

16:1-14 Asa seeks the aid of the Syrians, His death. - A plain and faithful reproof was given to Asa by a prophet of the Lord, for making a league with Syria. God is displeased when he is distrusted, and when an arm of flesh is relied on, more than his power and goodness. It is foolish to lean on a broken reed, when we have the Rock of ages to rely upon. To convince Asa of his folly, the prophet shows that he, of all men, had no reason to distrust God, who had found him such a powerful Helper. The many experiences we have had of the goodness of God to us, aggravate our distrust of him. But see how deceitful our hearts are! we trust in God when we have nothing else to trust to, when need drives us to him; but when we have other things to stay on, we are apt to depend too much on them. Observe Asa's displeasure at this reproof. What is man, when God leaves him to himself! He that abused his power for persecuting God's prophet, was left to himself, to abuse it further for crushing his own subjects. Two years before he died, Asa was diseased in his feet. Making use of physicians was his duty; but trusting to them, and expecting that from them which was to be had from God only, were his sin and folly. In all conflicts and sufferings we need especially to look to our own hearts, that they may be perfect towards God, by faith, patience, and obedience.
