8 In his days the Edomites revolted against Judah's authority, and made a king over themselves. 9 So Jehoram went out with his officers, and all his chariots with him. And he rose by night and attacked the Edomites who had surrounded him and the captains of the chariots. 10 Thus Edom has been in revolt against Judah's authority to this day. At that time Libnah revolted against his rule, because he had forsaken the Lord God of his fathers. 11 Moreover he made high places in the mountains of Judah, and caused the inhabitants of Jerusalem to commit harlotry, and led Judah astray.
12 And a letter came to him from Elijah the prophet, saying, Thus says the Lord God of your father David: Because you have not walked in the ways of Jehoshaphat your father, or in the ways of Asa king of Judah, 13 but have walked in the way of the kings of Israel, and have made Judah and the inhabitants of Jerusalem to play the harlot like the harlotry of the house of Ahab, and also have killed your brothers, those of your father's household, who were better than yourself, 14 behold, the Lord will strike your people with a serious affliction--your children, your wives, and all your possessions; 15 and you will become very sick with a disease of your intestines, until your intestines come out by reason of the sickness, day by day. 16 Moreover the Lord stirred up against Jehoram the spirit of the Philistines and the Arabians who were near the Ethiopians. 17 And they came up into Judah and invaded it, and carried away all the possessions that were found in the king's house, and also his sons and his wives, so that there was not a son left to him except Jehoahaz, the youngest of his sons.

(Read 2 Chronicles 21:1-11)
Jehoram hated his brethren, and slew them, for the same reason that Cain hated Abel, and slew him, because their piety condemned his impiety. In the mystery of Providence such men sometimes prosper for a time; but the Lord has righteous purposes in permitting such events, part of which may now be made out, and the rest will be seen hereafter.
Commentary on 2 Chronicles 21:12-20
(Read 2 Chronicles 21:12-20)
A warning from God was sent to Jehoram. The Spirit of prophecy might direct Elijah to prepare this writing in the foresight of Jehoram's crimes. He is plainly told that his sin should certainly ruin him. But no marvel that sinners are not frightened from sin, and to repentance, by the threatenings of misery in another world, when the certainty of misery in this world, the sinking of their estates, and the ruin of their health, will not restrain them from vicious courses. See Jehoram here stripped of all his comforts. Thus God plainly showed that the controversy was with him, and his house. He had slain all his brethren to strengthen himself; now, all his sons are slain but one. David's house must not be wholly destroyed, like those of Israel's kings, because a blessing was in it; that of the Messiah. Good men may be afflicted with diseases; but to them they are fatherly chastisements, and by the support of Divine consolations the soul may dwell at ease, even when the body lies in pain. To be sick and poor, sick and solitary, but especially to be sick and in sin, sick and under the curse of God, sick and without grace to bear it, is a most deplorable case. Wickedness and profaneness make men despicable, even in the eyes of those who have but little religion.
