2 Chronicles 21:19-20

19Then it happened in the course of time, after the end of two years, that his intestines came out because of his sickness; so he died in severe pain. And his people made no burning for him, like the burning for his fathers.

20He was thirty-two years old when he became king. He reigned in Jerusalem eight years and, to no one’s sorrow, departed. However they buried him in the City of David, but not in the tombs of the kings.
