Commentaries:
Things got so bad that Elijah, who had been carried away in a whirlwind about seven or eight years before, felt compelled to send a letter to Jehoram.
The fact that Jehoram was not buried with the other kings indicates the regard in which he was held by his subjects. This tragedy began with a foolish marriage arrangement, which had tragic results for Judah, because Jehoram preferred to follow his evil wife rather than his godly father. Jehoram's evil was so pernicious—it just kept growing and growing—that the people refused to bury him with the other kings. He died unregretted and unlamented. No one cried at his death, yet this evil man is on the list of Christ forebears.
