2 Chronicles 21:8-10

In his days the Edomites revolted from under the dominion of Judah, and made themselves a king.

Then Jehoram went forth with his princes, and all his chariots with him: and he rose up by night, and smote the Edomites which compassed him in, and the captains of the chariots.

So the Edomites revolted from under the hand of Judah unto this day. The same time also did Libnah revolt from under his hand; because he had forsaken the LORD God of his fathers.
