8 In his days hath Edom revolted from under the hand of Judah, and cause a king to reign over them; 9 and Jehoram passeth over with his heads, and all the chariots with him, and it cometh to pass, he hath risen by night and smiteth the Edomites who are coming round against him, and the princes of the chariots, 10 and Edom revolteth from under the hand of Judah unto this day; then doth Libnah revolt at that time from under his hand, because he hath forsaken Jehovah, God of his fathers, 11 also, he hath made high places in the mountains of Judah, and causeth the inhabitants of Jerusalem to commit whoredom, and compelleth Judah.

12 And there cometh in unto him a writing from Elijah the prophet, saying, 'Thus said Jehovah, God of David thy father, Because that thou hast not walked in the ways of Jehoshaphat thy father, and in the ways of Asa king of Judah, 13 and thou dost walk in the way of the kings of Israel, and dost cause Judah and the inhabitants of Jerusalem to commit whoredom like the whoredoms of the house of Ahab, and also thy brethren, the house of thy father, who are better than thyself, thou hast slain; 14 lo, Jehovah is smiting—a great smiting—among thy people, and among thy sons, and among thy wives, and among all thy goods— 15 and thou, with many sicknesses, with disease of thy bowels, till thy bowels come out, by the sickness, day by day.' 16 And Jehovah waketh up against Jehoram the spirit of the Philistines, and of the Arabians, who 'are' beside the Cushim, 17 and they come up into Judah, and rend it, and take captive all the substance that is found at the house of the king, and also his sons, and his wives, and there hath not been left to him a son except Jehoahaz the youngest of his sons.

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.
