2 Kings 3:10

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.

13 Elisha, however, said to the king of Israel, “What have we to do with each other? Go to the prophets of your father and of your mother!” “No,” replied the king of Israel, “for it is the LORD who has summoned these three kings to deliver them into the hand of Moab.”

14 Then Elisha said, “As surely as the LORD of Hosts lives, before whom I stand, were it not for my regard for the presence of Jehoshaphat king of Judah, I would not look at you or acknowledge you.
