6 So King Joram promptly mustered the army of Israel and marched from Samaria. 7 On the way, he sent this message to King Jehoshaphat of Judah: "The king of Moab has rebelled against me. Will you join me in battle against him?" And Jehoshaphat replied, "Why, of course! You and I are as one. My troops are your troops, and my horses are your horses." 8 Then Jehoshaphat asked, "What route will we take?" "We will attack from the wilderness of Edom," Joram replied. 9 The king of Edom and his troops joined them, and all three armies traveled along a roundabout route through the wilderness for seven days. But there was no water for the men or their animals. 10 "What should we do?" the king of Israel cried out. "The Lord has brought the three of us here to let the king of Moab defeat us." 11 But King Jehoshaphat of Judah asked, "Is there no prophet of the Lord with us? If there is, we can ask the Lord what to do through him." One of King Joram's officers replied, "Elisha son of Shaphat is here. He used to be Elijah's personal assistant. " 12 Jehoshaphat said, "Yes, the Lord speaks through him." So the king of Israel, King Jehoshaphat of Judah, and the king of Edom went to consult with Elisha. 13 "Why are you coming to me?" Elisha asked the king of Israel. "Go to the pagan prophets of your father and mother!" But King Joram of Israel said, "No! For it was the Lord who called us three kings here-only to be defeated by the king of Moab!" 14 Elisha replied, "As surely as the Lord Almighty lives, whom I serve, I wouldn't even bother with you except for my respect for King Jehoshaphat of Judah. 15 Now bring me someone who can play the harp." While the harp was being played, the power of the Lord came upon Elisha, 16 and he said, "This is what the Lord says: This dry valley will be filled with pools of water! 17 You will see neither wind nor rain, says the Lord, but this valley will be filled with water. You will have plenty for yourselves and your cattle and other animals. 18 But this is only a simple thing for the Lord, for he will make you victorious over the army of Moab! 19 You will conquer the best of their towns, even the fortified ones. You will cut down all their good trees, stop up all their springs, and ruin all their good land with stones."
20 The next day at about the time when the morning sacrifice was offered, water suddenly appeared! It was flowing from the direction of Edom, and soon there was water everywhere. 21 Meanwhile, when the people of Moab heard about the three armies marching against them, they mobilized every man who was old enough to strap on a sword, and they stationed themselves along their border. 22 But when they got up the next morning, the sun was shining across the water, making it appear red to the Moabites-like blood. 23 "It's blood!" the Moabites exclaimed. "The three armies must have attacked and killed each other! Let's go, men of Moab, and collect the plunder!" 24 But when the Moabites arrived at the Israelite camp, the army of Israel rushed out and attacked them until they turned and ran. The army of Israel chased them into the land of Moab, destroying everything as they went.

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.
