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 Isa 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.
