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 who encompassed him, and the captains of the chariots: and the people fled into their tents.
22 Yet Edom revolted from under the hand of Judah to this day. Then Libnah revolted at the same time.
