Albert Barnes Commentary 2 Kings 14:20

"And they brought him upon horses; and he was buried at Jerusalem with his fathers in the city of David." — 2 Kings 14:20 (ASV)

They brought him on horses - that is, they conveyed his body back to Jerusalem in the royal chariot. The combination of relentless animosity against the living prince with the deepest respect for his dead remains is very characteristic of an Eastern people.
