8In the days of Jehoram, Edom rebelled against the hand of Judah and appointed their own king.
9So Jehoram crossed into Edom with his officers and all his chariots. When the Edomites surrounded him and his chariot commanders, he rose up and attacked by night.
10So to this day Edom has been in rebellion against the hand of Judah. Likewise, Libnah rebelled against his rule at the same time, because Jehoram had forsaken the LORD, the God of his fathers.
