2 Chronicles 21
8 Ref In his time Edom made themselves free from the rule of Judah, and took a king for themselves.
9 Then Jehoram went over with his captains and all his war-carriages ... made an attack by night on the Edomites, whose forces were all round him ... on the captains of the war-carriages.
10 Ref So Edom made themselves free from the rule of Judah, to this day: and at the same time Libnah made itself free from his rule; because he was turned away from the Lord, the God of his fathers.
