2 Chronicles 21:12-15

12Then a letter came to Jehoram from Elijah the prophet, saying, “Thus says the Lord God of David your father (ancestor): ‘Because you have not walked in the ways of your father Jehoshaphat nor in the ways of Asa king of Judah,

13but have walked in the way of the kings of Israel, and caused Judah and the inhabitants of Jerusalem to be unfaithful [to God] as the house of Ahab was unfaithful, and you have also murdered your brothers, your father’s house (your own family), who were better than you,

14behold, the Lord is going to strike your people, your sons, your wives, and all your possessions with a great disaster;

15and you will suffer a severe illness, an intestinal disease, until your intestines come out because of the sickness, day after day.’ ”
