2 Chronicles 21:18-20

18After all this happened, the Lord afflicted him with an incurable intestinal disease.

19After about two years his intestines came out because of the disease, so that he died a very painful death. His people did not make a bonfire to honor him, as they had done for his ancestors.

20Jehoram was thirty-two years old when he became king and he reigned eight years in Jerusalem. No one regretted his death; he was buried in the City of David, but not in the royal tombs.
