Melachim Bais 3:19 Meaning and Commentary

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.

Melachim Bais 3:19 In-Context

17 For thus saith Hashem, Ye shall not see ruach, neither shall ye see geshem; yet this valley shall be filled with mayim, that ye may drink, both ye, and your cattle, and your behemah (livestock).

18 And this is but a light thing in the eyes of Hashem; He will deliver Mo’av also into your yad.

19 And ye shall strike every fortified city, every ir mivchor, and shall fell every etz tov, stop up kol ma’yan mayim, mar every good allotment of land with avanim.

20 And it came to pass in the boker, when the minchah was offered, that, hinei, there came mayim by the derech of Edom, and HaAretz was filled with mayim.

21 And when kol Mo’av heard that the melachim were come up to fight against them, they gathered all that could bear arms, and older, and stood at the border.
