John Wesley on Isaiah 21:1

The plain - Of Babylon, which lay in a very plain country. And the title of the sea might well be given to the waters of Babylon, because of the great plenty and multitude of them. South - In those parts which lay southward from Judea, where there were many and great deserts. Pass through - As meeting with no opposition. It - The burden or judgment. Desert - From Media and Persia; a great desert lay between them and Chaldea. A terrible land - From the Medes, a warlike and formidable people.
