Deuteronomy 20:12-20

12 But if they will not make peace, and shall begin war against thee, thou shalt besiege it.
13 And when the Lord thy God shall deliver it into thy hands, thou shalt slay all that are therein of the male sex, with the edge of the sword,
14 Excepting women and children, cattle and other things, that are in the city. And thou shalt divide all the prey to the army, and thou shalt eat the spoils of thy enemies, which the Lord thy God shall give thee.
15 So shalt thou do to all cities that are at a great distance from thee, and are not of these cities which thou shalt receive in possession.
16 But of those cities that shall be given thee, thou shalt suffer none at all to live:
17 But shalt kill them with the edge of the sword, to wit, the Hethite, and the Amorrhite, and the Chanaanite, the Pherezite, and the Hevite, and the Jebusite, as the Lord thy God hath commanded thee:
18 Lest they teach you to do all the abominations which they have done to their gods: and you should sin against the Lord your God.
19 When thou hast besieged a city a long time, and hath compassed it with bulwarks, to take it, thou shalt not cut down the trees that may be eaten of, neither shalt thou spoil the country round about with axes: for it is a tree, and not a man, neither can it increase the number of them that fight against thee.
20 But if there be any trees that are not fruitful, but wild, and fit for other uses, cut them down, and make engines, until thou take the city, which fighteth against thee.

Deuteronomy 20:12-20 Meaning and Commentary

INTRODUCTION TO DEUTERONOMY 20

In this chapter rules are given to be observed in times of war. When a battle was near, a priest was to address the soldiers, and encourage them to fight, De 20:1-4, then the officers were to declare who might return home, De 20:5-9 when an enemy's city was approached, peace was to be proclaimed on certain conditions, which, if accepted of, the inhabitants were to be tributaries and servants, but if not, when taken, all were to be put to the sword, excepting women, children, and cattle, De 20:10-15, but those of the seven nations were to be utterly destroyed, De 20:16-18, and, during a siege, no trees bearing fruit fit for food were to be cut down, De 20:19.
