8 In his days Edom revolted from under the hand of Judah, and made a king over themselves. 9 Then Jehoram passed over with his captains, and all his chariots with him: and he rose up by night, and struck the Edomites who surrounded him, along with the captains of the chariots. 10 So Edom revolted from under the hand of Judah to this day: then did Libnah revolt at the same time from under his hand, because he had forsaken Yahweh, the God of his fathers. 11 Moreover he made high places in the mountains of Judah, and made the inhabitants of Jerusalem to play the prostitute, and led Judah astray.
12 There came a writing to him from Elijah the prophet, saying, Thus says Yahweh, the God of David your father, Because you have not walked in the ways of Jehoshaphat your father, nor 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 prostitute, like as the house of Ahab did, and also have slain your brothers of your father’s house, who were better than yourself: 14 behold, Yahweh will strike with a great plague your people, and your children, and your wives, and all your substance; 15 and you shall have great sickness by disease of your bowels, until your bowels fall out by reason of the sickness, day by day. 16 Yahweh stirred up against Jehoram the spirit of the Philistines, and of the Arabians who are beside the Ethiopians: 17 and they came up against Judah, and broke into it, and carried away all the substance that was found in the king’s house, and his sons also, and his wives; so that there was never a son left him, save 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.
