(18) Is but a light thing.--Will be a light thing (1Kings 16:31).

He will deliver the Moabites.--The contrary of Jehoram's expectation (2Kings 3:10; 2Kings 3:13).

Verse 18. - And this is but a light thing in the sight of the Lord. God, the Author of nature, has full control over nature, and it is an easy matter for him to produce at will any natural phenomena. It is otherwise when the stubborn element of the human will is brought into play. Then difficulty may arise. He will deliver the Moabites also into your hand. It would be better to translate, he will also deliver (see the Revised Version).

3:6-19 The king of Israel laments their distress, and the danger they were in. He called these kings together, yet he charges it upon Providence. Thus the foolishness of man perverteth his way, and then his heart fretteth against the Lord, Pr 19:3. It was well that Jehoshaphat inquired of the Lord now, but it had been much better if he had done it before he engaged in this war. Good men sometimes neglect their duty, till necessity and affliction drive them to it. Wicked people often fare the better for the friendship and society of the godly. To try their faith and obedience, Elisha bids them make the valley full of pits to receive water. Those who expect God's blessings, must dig pools for the rain to fill, as in the valley of Baca, and thus make even that a well, Ps 84:6. We need not inquire whence the water came. God is not tied to second causes. They that sincerely seek for the dew of God's grace, shall have it, and by it be made more than conquerors.And this is but a light thing in the sight of the Lord,.... To give them such a plenty of water in such an extraordinary manner: he would do for them what was greater, not only save them from falling into the hand of Moab, which they feared,

but he wilt deliver the Moabites into your hands; which was more than was asked for, or expected.
