2 Kings 8:20-24

In his days Edom revolted from under the hand of Judah, and made a king over themselves.

So Joram went over to Zair, and all the chariots with him: and he rose by night, and smote the Edomites which compassed him about, and the captains of the chariots: and the people fled into their tents.

Yet Edom revolted from under the hand of Judah unto this day. Then Libnah revolted at the same time.

And the rest of the acts of Joram, and all that he did, are they not written in the book of the chronicles of the kings of Judah?

And Joram slept with his fathers, and was buried with his fathers in the city of David: and Ahaziah his son reigned in his stead.
