Devarim 20:19-20

Orthodox Jewish Bible

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.
