Deuteronomy 20:19 ESV

19 "When you besiege a city for a long time, making war against it in order to take it, 1you shall not destroy its trees by wielding an axe against them. You may eat from them, but you shall not cut them down. Are the trees in the field human, that they should be besieged by you?
