2 Chronicles 21:10
So the Edomites revolted from under the hand of Judah unto this day. The same time also did Libnah revolt from under his hand; because he had forsaken the LORD God of his fathers. So the Edomites revolted from under the hand of Judah unto this day. The same time also did Libnah revolt from under his hand; because he had forsaken the LORD God of his fathers.
The verse concerns Jehoram of Judah, the son of Jehoshaphat, whose course after Jehoshaphat died is set forth as forsaking the LORD God of his fathers. He was closely related by marriage to the daughter of Ahab and Jezebel, and under that influence he turned from the godly example before him. Instead of walking in the ways of Asa and Jehoshaphat, he walked in the way of the kings of Israel. After the pattern of the house of Ahab he followed after Baal.
He made high places in the mountains of Judah. By those high places and his example he caused the inhabitants of Jerusalem to be unfaithful and compelled Judah to follow in the same unfaithfulness. He also secured his position by violence, killing his own brothers, who were better than himself. The revolts of Edom and Libnah recorded in the verse came as the direct result of this forsaking of the LORD God of his fathers.
He was not permitted to continue unreproved, but received a written message from Elijah. That message declared that the LORD would strike his people, his children, his wives, and his goods with a great plague, and would strike him himself with great sickness. In fulfillment, the LORD stirred up the Philistines and the Arabians near the Ethiopians, who entered Judah, broke into it, and carried away all the goods of the king's house with his sons and wives, so that only his youngest son Jehoahaz remained. Afterward the LORD struck Jehoram in his bowels with an incurable disease, from which he died after two years.
