2 Chronicles 21:12-15

12Then a letter came to Jehoram from Elijah the prophet, which stated:

“This is what the LORD, the God of your father David, says:

‘You have not walked in the ways of your father Jehoshaphat or of Asa king of Judah, 13but you have walked in the ways of the kings of Israel and have caused Judah and the people of Jerusalem to prostitute themselves, just as the house of Ahab prostituted itself. You have also killed your brothers, your father’s family, who were better than you.

14So behold, the LORD is about to strike your people, your sons, your wives, and all your possessions with a serious blow. 15And day after day you yourself will suffer from a severe illness, a disease of your bowels, until it causes your bowels to come out.’”
