3:15 But now bring me a minstrel. And it came to pass, when the minstrel {l} played, that the hand of the LORD came upon him.
(l) He sang songs to God's glory, and so stirred up the prophets heart to prophecy.
3:15 Minstrel - One that can sing and play upon a musical instrument. This he requires, that his mind which had been disturbed at the sight of wicked Jehoram, might be composed, and that he might be excited to more fervent prayer whereby he was prepared to receive the prophetic inspiration. Those that desire communion with God must keep their spirits quiet and serene. All hurry of spirit, and all turbulent passions, make us unfit for divine visitations. The hand, and c. - The spirit of prophecy, so called, to note that it was no natural nor acquired virtue inherent in him; but a singular gift of God, given to whom and when he pleased.
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.
