Thy pomp is brought down to the grave; all thy glory is lost and buried with thee. The noise of thy viols; all thy musical and melodious instruments, which were much used in Babylon, Daniel 3:5,7,10, and were doubtless used in Belshazzar's solemn feast, Daniel 5:1, at which time the city was taken; to which possibly the prophet here alludes. The worm is spread under thee, instead of those rich and stately carpets upon which thou didst frequently tread.
