2 Kings 3:8

4 Now Mesha king of Moab was a sheep breeder, and he would render to the king of Israel a hundred thousand lambs and the wool of a hundred thousand rams.

5 But after the death of Ahab, the king of Moab rebelled against the king of Israel.

6 So at that time King Jehoram set out from Samaria and mobilized all Israel.

7 And he sent a message to Jehoshaphat king of Judah: “The king of Moab has rebelled against me. Will you go with me to fight against Moab?” “I will go,” replied Jehoshaphat. “I am like you, my people are your people, and my horses are your horses.”

8 Then he asked, “Which way shall we go up?” “By way of the Desert of Edom,” replied Joram.

9 So the king of Israel, the king of Judah, and the king of Edom set out, and after they had traveled a roundabout route for seven days, they had no water for their army or for their animals.

10 “Alas,” said the king of Israel, “for the LORD has summoned these three kings to deliver them into the hand of Moab!”

11 But Jehoshaphat asked, “Is there no prophet of the LORD here? Let us inquire of the LORD through him.” And one of the servants of the king of Israel answered, “Elisha son of Shaphat is here. He used to pour water on the hands of Elijah.”

12 Jehoshaphat affirmed, “The word of the LORD is with him.” So the king of Israel and Jehoshaphat and the king of Edom went down to him.
