6 But Jehoram followed the example of the kings of Israel and was as wicked as King Ahab, for he had married one of Ahab's daughters. So Jehoram did what was evil in the Lord 's sight. 7 But the Lord did not want to destroy David's dynasty, for he had made a covenant with David and promised that his descendants would continue to rule, shining like a lamp forever. 8 During Jehoram's reign, the Edomites revolted against Judah and crowned their own king. 9 So Jehoram went out with his full army and all his chariots. The Edomites surrounded him and his chariot commanders, but he went out at night and attacked them under cover of darkness. 10 Even so, Edom has been independent from Judah to this day. The town of Libnah also revolted about that same time. All this happened because Jehoram had abandoned the Lord, the God of his ancestors. 11 He had built pagan shrines in the hill country of Judah and had led the people of Jerusalem and Judah to give themselves to pagan gods and to go astray.
12 Then Elijah the prophet wrote Jehoram this letter: "This is what the Lord, the God of your ancestor David, says: You have not followed the good example of your father, Jehoshaphat, or your grandfather King Asa of Judah. 13 Instead, you have been as evil as the kings of Israel. You have led the people of Jerusalem and Judah to worship idols, just as King Ahab did in Israel. And you have even killed your own brothers, men who were better than you. 14 So now the Lord is about to strike you, your people, your children, your wives, and all that is yours with a heavy blow. 15 You yourself will suffer with a severe intestinal disease that will get worse each day until your bowels come out." 16 Then the Lord stirred up the Philistines and the Arabs, who lived near the Ethiopians, to attack Jehoram. 17 They marched against Judah, broke down its defenses, and carried away everything of value in the royal palace, including the king's sons and his wives. Only his youngest son, Ahaziah, was spared. 18 After all this, the Lord struck Jehoram with an incurable intestinal disease. 19 The disease grew worse and worse, and at the end of two years it caused his bowels to come out, and he died in agony. His people did not build a great funeral fire to honor him as they had done for his ancestors. 20 Jehoram was thirty-two years old when he became king, and he reigned in Jerusalem eight years. No one was sorry when he died. They buried him in the City of David, but not in the royal cemetery.

Commentary on 2 Chronicles 21:1-11
(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.
