2 Kings 3:7-9

New Revised Standard Version, Anglicised Catholic Edition

⁷ As he went he sent word to King Jehoshaphat of Judah, ‘The king of Moab has rebelled against me; will you go with me to battle against Moab?’ He answered, ‘I will; I am with you, my people are your people, my horses are your horses.’ ⁸ Then he asked, ‘By which way shall we march?’ Jehoram answered, ‘By the way of the wilderness of Edom.’

⁹ So the king of Israel, the king of Judah, and the king of Edom set out; and when they had made a roundabout march of seven days, there was no water for the army or for the animals that were with them.
