John Calvin Commentary Isaiah 15:6

"For the waters of Nimrim shall be desolate; for the grass is withered away, the tender grass faileth, there is no green thing." — Isaiah 15:6 (ASV)

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 were probably highly necessary for that dry and parched country, as soils of that kind produce nothing without irrigation.

Although the style is exaggerated, yet nothing is stated but what is strictly true. For the Prophet did not go beyond proper bounds; rather, he found it necessary to use bold expressions to suit the people's ignorance. He did this to inform them that a land deprived of God's blessing will be like a desert without any beauty.
