2 Kings 8:20-21
2 Kings 8: 20 to 21
20 In his days Edom revolted from under the hand of Judah, and made a king over themselves.
21 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.
