8 In his time Edom made themselves free from the rule of Judah, and took a king for themselves. 9 Then Jehoram went over with his captains and all his war-carriages ... made an attack by night on the Edomites, whose forces were all round him ... on the captains of the war-carriages. 10 So Edom made themselves free from the rule of Judah, to this day: and at the same time Libnah made itself free from his rule; because he was turned away from the Lord, the God of his fathers. 11 And more than this, he made high places in the mountains of Judah, teaching the people of Jerusalem to go after false gods, and guiding Judah away from the true way.
12 And a letter came to him from Elijah the prophet, saying, The Lord, the God of your father David, says, Because you have not kept to the ways of your father Jehoshaphat or the ways of Asa, king of Judah, 13 But have gone in the way of the kings of Israel, and have made Judah and the people of Jerusalem go after false gods, as the family of Ahab did: and because you have put to death your father's sons, your brothers, who were better than yourself: 14 Now, truly, the Lord will send a great destruction on your people and your children and your wives and everything which is yours: 15 And you yourself will undergo the cruel pains of a disease in your stomach, so that day by day your inside will be falling out because of the disease. 16 Then the Philistines and the Arabians, who are by Ethiopia, were moved by the Lord to make war on Jehoram; 17 And they came up against Judah, forcing a way into it, and took away all the goods in the king's house, as well as his sons and his wives; so that he had no son but only Jehoahaz, the youngest.

(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.
