A letter came to him from the prophet Elijah, saying: "Thus says the Lord, the God of your father David: Because you have not walked in the ways of your father Jehoshaphat or in the ways of King Asa of Judah,
but have walked in the way of the kings of Israel, and have led Judah and the inhabitants of Jerusalem into unfaithfulness, as the house of Ahab led Israel into unfaithfulness, and because you also have killed your brothers, members of your father's house, who were better than yourself,
see, the Lord will bring a great plague on your people, your children, your wives, and all your possessions,
and you yourself will have a severe sickness with a disease of your bowels, until your bowels come out, day after day, because of the disease."
The Lord aroused against Jehoram the anger of the Philistines and of the Arabs who are near the Ethiopians.
References for 2 Chronicles 21:16
They came up against Judah, invaded it, and carried away all the possessions they found that belonged to the king's house, along with his sons and his wives, so that no son was left to him except Jehoahaz, his youngest son.
After all this the Lord struck him in his bowels with an incurable disease.
In 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 ancestors.
