Matthew Henry's Complete Bible Commentary

Verses 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, 2 Chronicles 18:31. 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, 2 Chronicles 18:33. 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. MHBCC 386.7
