Deuteronomy 20:18

¹⁶Of these ye shall not take anything alive;

¹⁷but ye shall surely curse them, the Hittite, and the Amorite, and the Canaanite, and the Perizzite, and the Hivite, and the Jebusite, and the Girgashite; as the Lord thy God commanded thee:

— Deuteronomy 20:18 —

¹⁹And if thou shouldest besiege a city many days to prevail against it by war to take it, thou shalt not destroy its trees, by applying an iron tool to them, but thou shalt eat of it, and shalt not cut it down: Is the tree that is in the field a man, to enter before thee into the work of the siege?

²⁰But the tree which thou knowest to be not fruit bearing, this thou shalt destroy and cut down; and thou shalt construct a mound against the city, which makes war against thee, until it be delivered up.
