2 Chronicles 21:12-15

12Then 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.

13Instead, 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.

14So now the Lord is about to strike you, your people, your children, your wives, and all that is yours with a heavy blow.

15You yourself will suffer with a severe intestinal disease that will get worse each day until your bowels come out.”
