ERV(i)
20 In his days Edom revolted from under the hand of Judah, and made a king over themselves.
21 Then Joram passed over to Zair, and all his chariots with him: and he rose up by night, and smote the Edomites which compassed him about, and the captains of the chariots: and the people fled to their tents.
22 So Edom revolted from under the hand of Judah, unto this day. Then did Libnah revolt at the same time.
