John Calvin Commentary Isaiah 14:11

"Thy pomp is brought down to Sheol, [and] the noise of thy viols: the worm is spread under thee, and worms cover thee." — Isaiah 14:11 (ASV)

Thy pomp is laid down in the grave. He mentions royal pomp so that this change may be more attentively considered by comparing the latter with the former; and he shows that that pomp could not prevent him from being reduced to the same level as other men. Under the term musical instruments, he includes all the luxuries and enjoyments in which kings are accustomed to indulge, because not only does the sweetness of music cause them to forget death, but their mad sound also drives away all sadness and, in some respects, stupefies the minds of men.

The worm is spread under thee, and the worms cover thee. In this second clause, the dead say jestingly, “You have obtained a bed worthy of you; for the worms serve you for tapestry or a soft couch, and the worm serves for a splendid coverlet.” In short, there is exhibited to us here a lively painting of the foolish confidence of men, who, intoxicated with their present enjoyments and prosperity, flatter themselves. This doctrine should be carefully pondered; for though men are well aware of their condition and have death before their eyes, yet, overcome by ambition, soothed by pleasures, and even fascinated by empty show, they forget themselves.
