Matthew Henry's Concise Commentary18:1-34 Jehoshaphat's alliance with Ahab. - This history we read in 1Ki 22. Abundant riches and honour give large opportunities of doing good, but they are attended with many snares and temptations. Men do not know much of the artifices of Satan and the deceitfulness of their own hearts, when they covet riches with the idea of being able to do good with them. What can hurt those whom God will protect? What can shelter those whom God will destroy? Jehoshaphat is safe in his robes, Ahab killed in his armour; for the race is not to the swift, nor the battle to the strong. We should be cautious of entangling ourselves in the worldly undertakings of evil men; and still more we should avoid engaging in their sinful projects. But, when they call upon him, God can and will bring his faithful people out of the difficulties and dangers into which they have sinfully run themselves. He has all hearts in his hand, so that he easily rescues them. Blessed is the man that putteth his trust in the Lord.
Matthew Henry's Whole Bible CommentaryVerses 28-34 We have here, 1. Good Jehoshaphat exposing himself in his robes, thereby endangered, and yet delivered. We have reason to think that Ahab, while he pretended friendship, really aimed at Jehoshaphat's life, to take him off, that he might have the management of his successor, who was his son-in-law, else he would never have advised him to enter into the battle with his robes on, which was but to make himself an easy mark to the enemy: and, if really he intended that, it was as unprincipled a piece of treachery as ever man was guilty of, and justly was he himself taken in the pit he digged for his friend. The enemy had soon an eye upon the robes, and vigorously attacked the unwary prince who now, when it was too late, wished himself in the habit of the poorest soldier, rather than in his princely raiment. he cried out, either to his friends to relieve him (but Ahab took no care of that), or to his enemies, to rectify their mistake, and let them know that he was not the king of Israel. Or perhaps he cried to God for succour and deliverance (to whom else should he cry?) and he found it was not in vain: The Lord helped him out of his distress, by moving the captains to depart from him, v. 31. God has all men's hearts in his hand, and turns them as he pleases, contrary to their own first intentions, to serve his purposes. Many are moved unaccountably both to themselves and others, but an invisible power moves them. 2. Wicked Ahab disguising himself, arming himself thereby as he thought securing himself, and yet slain, v. 33. No art, no arms, can save those whom God has appointed to ruin. What can hurt those whom God will protect? And what can shelter those whom God will destroy? Jehoshaphat is safe in his robes, Ahab killed in his armour; for the race is not to the swift nor the battle to the strong. |
