2 Kings 8:19-22
English Standard Version
20In his days Edom revolted from the rule of Judah and set up a king of their own.
21Then Joram passed over to Zair with all his chariots and rose by night, and he and his chariot commanders struck the Edomites who had surrounded him, but his army fled home.
22So Edom revolted from the rule of Judah to this day. Then Libnah revolted at the same time.
