Charles Ellicott Commentary Isaiah 14:18

"All the kings of the nations, all of them, sleep in glory, every one in his own house." — Isaiah 14:18 (ASV)

All the kings of the nations ... —The “house” in which the monarchs lie is, of course, their sepulchre. Such sepulchres, as in the case of the pyramid graves of the Egyptian kings, the “eternal home” as they themselves called it , were often almost literally the “house,” or palace, of the dead.
