2 Chronicles 21:8-10

8While Jehoram was king, Edom's people turned against Judah. They would no longer accept the king of Judah's authority over them. They decided to have their own king.

9So King Jehoram travelled to Zair with his army officers and all his chariots. The Edomite army came and they were all around him. But that night, Jehoram and his officers attacked the Edomites and they escaped.

10Even today, Edom's people do not obey the rulers of Judah. The people of Libnah city also turned against Judah at the same time. That happened because Jehoram had turned away from the Lord, the God of his ancestors.
