2 Kings 3

11. which poured water on the hands of Elijah--that is, was his servant--this being one of the common offices of a servant. The phrase is used here as synonymous with "a true and eminent prophet," who will reveal God's will to us.

13, 14. What have I to do with thee? &c.--Wishing to produce a deep spirit of humility and contrition, Elisha gave a stern repulse to the king of Israel, accompanied by a sarcastic sneer, in bidding him go and consult Baal and his soothsayers. But the distressed condition, especially the imploring language, of the royal suppliants, who acknowledged the hand of the Lord in this distress, drew from the prophet the solemn assurance, that solely out of respect to Jehoshaphat, the Lord's true servant, did he take any interest in Jehoram.

15. bring me a minstrel--The effect of music in soothing the mind is much regarded in the East; and it appears that the ancient prophets, before entering their work, commonly resorted to it, as a preparative, by praise and prayer, to their receiving the prophetic afflatus.
the hand of the Lord--a phrase significantly implying that the gift of prophecy was not a natural or inherent gift, but conferred by the power and grace of God.

16. Make this valley full of ditches--capable of holding water.

17. Ye shall not see wind--It is common in the East to speak of seeing wind, from the clouds of straw, dust, or sand, that are often whirled into the air, after a long drought.

20-24. when the meat offering was offered--that is, at the time of the morning sacrifice, accompanied, doubtless, with solemn prayers; and these led, it may be, by Elisha on this occasion, as on a similar one by Elijah ( 1 Kings 18:36 ).
behold, there came water by the way of Edom--Far from the Israelitish camp, in the eastern mountains of Edom, a great fall of rain, a kind of cloudburst, took place, by which the wady was at once filled, but they saw neither the wind nor the rains. The divine interposition was shown by introducing the laws of nature to the determined end in the predetermined way [KEIL]. It brought not only aid to the Israelitish army in their distress, by a plentiful supply of water, but destruction on the Moabites, who, perceiving the water, under the refulgent rays of the morning sun, red like blood, concluded the confederate kings had quarrelled and deluged the field with their mutual slaughter; so that, rushing to their camp in full expectation of great spoil, they were met by the Israelites, who, prepared for battle, fought and pursued them. Their country was laid waste in the way, which has always been considered the greatest desolation in the East.

25. Kir-haraseth--(now Kerak)--Castle of Moab--then, probably, the only fortress in the land.

27. took his eldest son that should have reigned in his stead, and offered him for a burnt offering, &c.--By this deed of horror, to which the allied army drove the king of Moab, a divine judgment came upon Israel; that is, the besiegers feared the anger of God, which they had incurred by giving occasion to the human sacrifice forbidden in the law ( Leviticus 18:21 , 20:3 ), and hastily raised the siege.
