Deuteronomy 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 ) .

Deuteronomy 20:20 In-Context

18 Otherwise, they will teach you to do all the disgusting things they do for their gods, and you will sin against the LORD your God.

19 This is what you must do whenever you blockade a city for a long time in order to capture it in war. Don't harm any of its fruit trees with an ax. You can eat the fruit. Never cut those trees down, because the trees of the field are not people you have come to blockade.

20 You may destroy trees that you know are not fruit trees. You may cut them down and use them in your blockade until you capture the city.
