12 And a letter came to him from Elijah the prophet, saying, "Thus says the Lord, the God of David your father, 'Because you have not walked in the ways of Jehoshaphat your father, or in the ways of Asa king of Judah, 13 but have walked in the way of the kings of Israel and have enticed Judah and the inhabitants of Jerusalem into whoredom, as the house of Ahab led Israel into whoredom, and also you have killed your brothers, of your father's house, who were better than yourself, 14 behold, the Lord will bring a great plague on your people, your children, your wives, and all your possessions, 15 and you yourself will have a severe sickness with a disease of your bowels, until your bowels come out because of the disease, day by day.'" 16 And the Lord stirred up against Jehoram the anger[1] of the Philistines and of the Arabians who are near the Ethiopians. 17 And they came up against Judah and invaded it and carried away all the possessions they found that belonged to the king's house, and also his sons and his wives, so that no son was left to him except Jehoahaz, his youngest son. 18 And after all this the Lord struck him in his bowels with an incurable disease. 19 In the course of time, at the end of two years, his bowels came out because of the disease, and he died in great agony. His people made no fire in his honor, like the fires made for his fathers. 20 He was thirty-two years old when he began to reign, and he reigned eight years in Jerusalem. And he departed with no one's regret. They buried him in the city of David, but not in the tombs of the kings.

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.
