Deuteronomy 20:18-20

21st Century King James Version

¹⁸ that they teach you not to do according to all their abominations which they have done unto their gods, so ye should sin against the Lord your God.

¹⁹ “When thou shalt besiege a city a long time, in making war against it to take it, thou shalt not destroy the trees thereof by forcing an ax against them, for thou mayest eat of them; and thou shalt not cut them down to employ them in the seige, for the tree of the field is man’s life.

²⁰ Only the trees which thou knowest are not trees for meat, thou shalt destroy and cut them down; and thou shalt build bulwarks against the city that maketh war with thee, until it be subdued.
