Deuteronomy 20:19-20

19When thou shalt besiege a cityH5892 a long time, in makingH3772 war against it to take it, thou shalt not destroyH7843 the treesH6086 thereof by wieldingH8610 an axeH1631 against them; for thou mayest eatH398 of them, and thou shalt not cutH3772 them downH3772; for is the treeH6086 of the fieldH7704 manH120, that it should be besieged of thee? 20OnlyH7535 the treesH6086 of which thou knowest that they are not treesH6086 for foodH3978, thou shalt destroyH7843 and cutH3772 them downH3381; and thou shalt buildH1129 bulwarks against the cityH5892 that maketh warH4421 with thee, until it fall.
