8 During Jehoram's reign, Edom revolted from Judah's rule and set up their own king. 9 Jehoram responded by setting out with his officers and chariots. Edom surrounded him, but in the middle of the night he and his charioteers broke through the lines and hit Edom hard. 10 Edom continues in revolt against Judah right up to the present. Even little Libnah revolted at that time. The evidence accumulated: Since Jehoram had abandoned God, the God of his ancestors, God was abandoning him. 11 He even went so far as to build pagan sacred shrines in the mountains of Judah. He brazenly led Jerusalem away from God, seducing the whole country.

12 One day he got a letter from Elijah the prophet. It read, "From God, the God of your ancestor David - a message: Because you have not kept to the ways of Jehoshaphat your father and Asa your grandfather, kings of Judah, 13 but have taken up with the ways of the kings of Israel in the north, leading Judah and Jerusalem away from God, going step by step down the apostate path of Ahab and his crew - why, you even killed your own brothers, all of them better men than you! - 14 God is going to afflict your people, your wives, your sons, and everything you have with a terrible plague. 15 And you are going to come down with a terrible disease of the colon, painful and humiliating." 16 The trouble started with an invasion. God incited the Philistines and the Arabs who lived near the Ethiopians to attack Jehoram. 17 They came to the borders of Judah, forced their way in, and plundered the place - robbing the royal palace of everything in it including his wives and sons. One son, his youngest, Ahaziah, was left behind.

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.
