the waters of Nimrim are a desolation; the grass is withered, the vegetation fails, the greenery is no more.
6. The waters of Nimrim. By an exaggerated form of expression he gives a more enlarged view of this desolation. He says that the grass is withered, which takes place when God leaves any soil destitute of all nourishment. The waters will be taken away, which probably were highly necessary for that dry and parched country; for soils of that kind produce nothing without irrigation.
Here the prophet further describes the woeful and piteous lamentations that should be heard throughout all the country of Moab when it should become a prey to the Assyrian army. "By this time the cry has gone round about all the borders of Moab," Isa 15:8. Every corner of the country has received the alarm, and is in the utmost confusion upon it.
Commenting on Isaiah 15:6-9
For the waters of Nimrim shall be desolate,.... Or dried up, through a great drought that should come upon the land at this time; or being defiled with the blood of the slain, as Jarchi: it may denote the well watered pastures about Nimrim, that should become the forage of the enemy, and be trodden under foot by its army, or be forsaken by the proprietors of them.
