So the king of Israel went with the king of Judah and the king of Edom. After they had marched seven days, there was no more water for the army or for their animals that were with them.
From then until now the country of Edom has fought against the rule of Judah. At the same time the people of Libnah also broke away from Jehoram because Jehoram left the Lord, the God of his ancestors.
So Jehoram went to Edom with all his commanders and chariots. The Edomites surrounded him and his chariot commanders, but Jehoram got up and attacked the Edomites at night.
