21:20 But not in the tombs of the kings
Yehoram does not behave as his forefathers before him did. By marrying into the House of Achav, and bringing idol worship into the kingdom, he betrays God. As such, he is punished heavily for his sins, and though he is not stripped of his kingdom, it loses its prominence and power. Upon his death, the people bury him apart from his ancestors. They realize that though he is of the Davidic line, because of his actions he is not a true Davidic king. Yehoram teaches us that the Davidic line is not merely an inheritance; it demands a certain code of behavior. So too with all birthrights. The way a person behaves means more than who his ancestors were.
