So the king of Israel went with the king of Judah and the king of Edom. And when they had made a circuitous march of seven days, there was no water for the army or for the beasts which followed them.
So Edom revolted from the rule of Judah to this day. At that time Libnah also revolted from his rule, because he had forsaken the Lord, the God of his fathers.
Then Jehoram passed over with his commanders and all his chariots, and he rose by night and smote the Edomites who had surrounded him and his chariot commanders.
