2 Kings 3:8-18

8 What route shall we take for the attack?" "We will go the long way through the wilderness of Edom," Joram answered.
9 So King Joram and the kings of Judah and Edom set out. After marching seven days, they ran out of water, and there was none left for the men or the pack animals.
10 "We're done for!" King Joram exclaimed. "The Lord has put the three of us at the mercy of the king of Moab!"
11 King Jehoshaphat asked, "Is there a prophet here through whom we can consult the Lord?" An officer of King Joram's forces answered, "Elisha son of Shaphat is here. He was Elijah's assistant."
12 "He is a true prophet," King Jehoshaphat said. So the three kings went to Elisha.
13 "Why should I help you?" Elisha said to the king of Israel. "Go and consult those prophets that your father and mother consulted." "No!" Joram replied. "It is the Lord who has put us three kings at the mercy of the king of Moab."
14 Elisha answered, "By the living Lord, whom I serve, I swear that I would have nothing to do with you if I didn't respect your ally, King Jehoshaphat of Judah.
15 Now get me a musician." As the musician played his harp, the power of the Lord came on Elisha,
16 and he said, "This is what the Lord says: "Dig ditches all over this dry stream bed.
17 Even though you will not see any rain or wind, this stream bed will be filled with water, and you, your livestock, and your pack animals will have plenty to drink.' "
18 And Elisha continued, "But this is an easy thing for the Lord to do; he will also give you victory over the Moabites.
