2nd Kings 3:9

6 And king Jehoram went out of Samaria the same time, and numbered all Israel.

7 And he went and sent to Jehoshaphat the king of Judah, saying, The king of Moab hath rebelled against me: wilt thou go with me against Moab to battle? And he said, I will go up: I am as thou art, my people as thy people, and my horses as thy horses.

8 And he said, Which way shall we go up? And he answered, The way through the wilderness of Edom.

9 So the king of Israel went, and the king of Judah, and the king of Edom: and they fetched a compass of seven days' journey: and there was no water for the host, and for the cattle that followed them.

10 And the king of Israel said, Alas! that the LORD hath called these three kings together, to deliver them into the hand of Moab!

11 But Jehoshaphat said, Is there not here a prophet of the LORD, that we may enquire of the LORD by him? And one of the king of Israel's servants answered and said, Here is Elisha the son of Shaphat, which poured water on the hands of Elijah.

12 And 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.
