Ye shall fell every good tree - This is not an infringement of the rule laid down in Deuteronomy 20:19-20. The Israelites were not forbidden to fell the fruit trees in an enemy’s country, as a part of the ravage of war, when they had no thoughts of occupying the country. The plan of thus injuring an enemy was probably in general use among the nations of these parts at the time. We see the destruction represented frequently on the Assyrian monuments and mentioned in the inscriptions of Egypt.
And stop all wells of water - The stoppage of wells was a common feature of ancient, and especially Oriental, warfare (compare Genesis 26:15-18).
Mar ... with stones - The exact converse of that suggested in Isaiah 5:2. The land in and about Palestine is so stony that the first work of the cultivator is to collect the surface stones together into heaps. An army marching through a land could easily undo this work, dispersing the stones thus gathered, and spreading them once more over the fields.
