6 So King Jehoram marched out of Samaria at that time and mustered all Israel. 7 As he went he sent word to King Jehoshaphat of Judah, "The king of Moab has rebelled against me; will you go with me to battle against Moab?" He answered, "I will; I am with you, my people are your people, my horses are your horses." 8 Then he asked, "By which way shall we march?" Jehoram answered, "By the way of the wilderness of Edom." 9 So the king of Israel, the king of Judah, and the king of Edom set out; and when they had made a roundabout march of seven days, there was no water for the army or for the animals that were with them. 10 Then the king of Israel said, "Alas! The Lord has summoned us, three kings, only to be handed over to Moab." 11 But Jehoshaphat said, "Is there no prophet of the Lord here, through whom we may inquire of the Lord?" Then one of the servants of the king of Israel answered, "Elisha son of Shaphat, who used to pour water on the hands of Elijah, is here." 12 Jehoshaphat said, "The word of the Lord is with him." So the king of Israel and Jehoshaphat and the king of Edom went down to him. 13 Elisha said to the king of Israel, "What have I to do with you? Go to your father's prophets or to your mother's." But the king of Israel said to him, "No; it is the Lord who has summoned us, three kings, only to be handed over to Moab." 14 Elisha said, "As the Lord of hosts lives, whom I serve, were it not that I have regard for King Jehoshaphat of Judah, I would give you neither a look nor a glance. 15 But get me a musician." And then, while the musician was playing, the power of the Lord came on him. 16 And he said, "Thus says the Lord, "I will make this wadi full of pools.' 17 For thus says the Lord, "You shall see neither wind nor rain, but the wadi shall be filled with water, so that you shall drink, you, your cattle, and your animals.' 18 This is only a trifle in the sight of the Lord, for he will also hand Moab over to you. 19 You shall conquer every fortified city and every choice city; every good tree you shall fell, all springs of water you shall stop up, and every good piece of land you shall ruin with stones."

20 The next day, about the time of the morning offering, suddenly water began to flow from the direction of Edom, until the country was filled with water. 21 When all the Moabites heard that the kings had come up to fight against them, all who were able to put on armor, from the youngest to the oldest, were called out and were drawn up at the frontier. 22 When they rose early in the morning, and the sun shone upon the water, the Moabites saw the water opposite them as red as blood. 23 They said, "This is blood; the kings must have fought together, and killed one another. Now then, Moab, to the spoil!" 24 But when they came to the camp of Israel, the Israelites rose up and attacked the Moabites, who fled before them; as they entered Moab they continued the attack.

Matthew Henry's Commentary on 2 Kings 3:6-24

Commentary on 2 Kings 3:6-19

(Read 2 Kings 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, Psalm 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.

Commentary on 2 Kings 3:20-27

(Read 2 Kings 3:20-27)

It is a blessing to be favoured with the company of those who have power with God, and can prevail by their prayers. A kingdom may be upheld and prosper, in consequence of the fervent prayers of those who are dear to God. May we place our highest regard upon such as are most precious in his account. When sinners are saying Peace, peace, destruction comes upon them: despair will follow their mad presumption. In Satan's service and at his suggestion, such horrid deeds have been done, as cause the natural feelings of the heart to shudder; like the king of Moab's sacrificing his son. It is well not to urge the worst of men to extremities; we should rather leave them to the judgment of God.
