Jamieson, Fausset and Brown on Isaiah 13:20

20. Literally fulfilled.

neither ... Arabian pitch tent--Not only shall it not be a permanent residence, but not even a temporary resting-place. The Arabs, through dread of evil spirits, and believing the ghost of Nimrod to haunt it, will not pass the night there (compare Is 13:21).

neither ... shepherds--The region was once most fertile; but owing to the Euphrates being now no longer kept within its former channels, it has become a stagnant marsh, unfit for flocks; and on the wastes of its ruins (bricks and cement) no grass grows.
