2-а хроніки 21:8

Never surely did any kingdom change its king so much for the worse as Judah did, when Jehoram, one of the vilest, succeeded Jehoshaphat, one of the best. Thus were they punished for not making a better use of Jehoshaphat's good government, and their disaffectedness (or coldness at least) to his reformation, Ch2 20:33. Those that knew not now to value a good king are justly plagued with a bad one. Here is, I. Jehoram's elevation to the throne (Ch2 21:1-3). II. The wicked course he took to establish himself in it, by the murder of his brethren (Ch2 21:4). III. The idolatries and other wickedness he was guilty of (Ch2 21:5, Ch2 21:6, Ch2 21:11). IV. The prophecy of Elijah against him (Ch2 21:12-15). V. The judgments of God upon him, in the revolt of his subjects from him (Ch2 21:8-10) and the success of his enemies against him (Ch2 21:16, Ch2 21:17). VI. His miserable sickness and inglorious exit (Ch2 21:18-20). VII. The preservation of the house of David notwithstanding (Ch2 21:7).

21:8-11 Jehoram’s disobedience caused him to lose the gains that Asa and Jehoshaphat had won. • the Edomites revolted: During Solomon’s reign, control of the territory of Edom gave Israel access to the rich trade from Arabia. The Edomites had also rebelled before Solomon’s death (1 Kgs 11:14-22), and were probably not under Rehoboam’s control. They apparently came under Judah’s control again following their defeat by Jehoshaphat (2 Chr 20:1-30; cp. 1 Kgs 22:47). • The town of Libnah was at the western end of the valley of Elah, on the border of the territory of the Philistines.
