2 Kings 3:7-9

New King James Version

⁷ Then he went and sent to Jehoshaphat king of Judah, saying, “The king of Moab has rebelled against me. Will you go with me to fight against Moab?”

And he said, “I will go up; ^(A)I am as you are, my people as your people, my horses as your horses.” ⁸ Then he said, “Which way shall we go up?”

And he answered, “By way of the Wilderness of Edom.”

⁹ So the king of Israel went with the king of Judah and the king of Edom, and they marched on that roundabout route seven days; and there was no water for the army, nor for the animals that followed them.
