John Calvin Commentary Isaiah 14:9

"Sheol from beneath is moved for thee to meet thee at thy coming; it stirreth up the dead for thee, even all the chief ones of the earth; it hath raised up from their thrones all the kings of the nations." — Isaiah 14:9 (ASV)

Hell from beneath is moved for you. As he had formerly attributed gladness to the trees, so now, by a similar figure, he attributes speech to the dead. He arouses them, as it were, from their graves, to mock the pride of this tyrant. The whole passage is ironical, and full of keen sarcasm.

At the approach of kings, the people tremble, and come forth to meet and receive them with pompous display. The Prophet makes a fictitious representation that when this tyrant dies and goes down to the grave, the dead will go forth to meet and honor him, but with such honor as he deserves. As if he had said, “Not only the living, but also the dead will rejoice at his death. The dead also will treat him respectfully according to what he deserves.”
