Devarim 20:20 Meaning and Commentary

Deuteronomy 20:20

Only the trees which thou knowest that they be not trees for
meat Which might be known not only by their not having fruit upon
them, but by other tokens, and even at a time of year when there was no fruit on any, which might be sometimes the season of a siege:

thou shalt destroy and cut them down;
if so to do was of any disservice to the enemy, or of any service to them, as follows; they had a liberty to destroy them if they would:

and thou shall build bulwarks against the city that maketh war, until
it be subdued;
build bulwarks of the trees cut down, and raise batteries with them, or make machines and engines of the wood of them, to cast stones into the city to annoy the inhabitants of it, in order to make them surrender, and until they do it. All this may be an emblem of the axe being to be laid to fruitless trees in a moral and spiritual sense; and of trees of righteousness, laden with the fruits of righteousness, the planting of the Lord, being preserved and never to be cut down or rooted up; see ( Matthew 3:10 ) ( Isaiah 60:3 ) ( Matthew 15:13 ) .

Devarim 20:20 In-Context

18 That they teach you not to do after all their to’evot (abominations) which they have done unto their elohim; so that ye would sin against Hashem Eloheichem.

19 When thou shalt besiege a town yamim rabbim, in making war against it to take it, thou shalt not destroy the trees thereof by forcing an axe against them; although thou mayest eat of them, thou shalt not cut them down. Are the etz hasadeh men that they should come under your siege?

20 Only the trees which thou knowest that they be not trees for food, thou shalt destroy and cut them down; and thou shalt build siege works against the town that maketh milchamah with thee, until it be subdued.
