2 Kings 3:19

And ye shall smite every fenced city and every choice city,
&c.] That is, the inhabitants of them with the sword, and demolish them also, ( 2 Kings 3:25 ) , and shall fell every good tree; which seems contrary to the law in ( Deuteronomy 20:19 ) , but that may respect trees belonging to a city when besieged only, or only to Canaanitish cities; or the law was now dispensed with, and that for this time only, to make the punishment of Moab the greater, for their rebellion and other sins:

and stop all wells of water;
which must be very distressing to those that survived the calamity of the sword:

and mar every good piece of land with stones;
as that it could not be ploughed and sowed, nor anything spring up and grow upon it.
