Deuteronomy 20:19

20:19 If you besiege a city for a long time while attempting to capture it, ¹  you must not chop down its trees, ²  for you may eat fruit ³  from them and should not cut them down. A tree in the field is not human that you should besiege it! ⁴ 

[20:19]  ¹ tn Heb “to fight against it to capture it.”

[20:19]  ² tn Heb “you must not destroy its trees by chopping them with an iron” (i.e., an ax).

[20:19]  ³ tn Heb “you may eat from them.” The direct object is not expressed; the word “fruit” is supplied in the translation for clarity.

[20:19]  ⁴ tn Heb “to go before you in siege.”
