“When you go out to war against your enemies, and see horses and
chariots and an army larger than your own, you shall not be afraid
of them, for the LORD your God is with you, who brought you up out
of the land of Egypt. And when you draw near to the battle, the
priest shall come forward and speak to the people and shall say to
them, ‘Hear, O Israel, today you are drawing near for battle
against your enemies: let not your heart faint. Do not fear or
panic or be in dread of them, for the LORD your God is he who goes
with you to fight for you against your enemies, to give you the
victory.’ Then the officers shall speak to the people, saying, ‘Is
there any man who has built a new house and has not dedicated it?
Let him go back to his house, lest he die in the battle and another
man dedicate it. And is there any man who has planted a vineyard
and has not enjoyed its fruit? Let him go back to his house, lest
he die in the battle and another man enjoy its fruit. And is there
any man who has betrothed a wife and has not taken her? Let him go
back to his house, lest he die in the battle and another man take
her.’ And the officers shall speak further to the people, and say,
‘Is there any man who is fearful and fainthearted? Let him go back
to his house, lest he make the heart of his fellows melt like his
own.’ And when the officers have finished speaking to the people,
then commanders shall be appointed at the head of the people.

 “When you draw near to a city to fight against it, offer terms of
peace to it. And if it responds to you peaceably and it opens to
you, then all the people who are found in it shall do forced labor
for you and shall serve you. But if it makes no peace with you, but
makes war against you, then you shall besiege it. And when the LORD
your God gives it into your hand, you shall put all its males to
the sword, but the women and the little ones, the livestock, and
everything else in the city, all its spoil, you shall take as
plunder for yourselves. And you shall enjoy the spoil of your
enemies, which the LORD your God has given you. Thus you shall do
to all the cities that are very far from you, which are not cities
of the nations here. But in the cities of these peoples that the
LORD your God is giving you for an inheritance, you shall save
alive nothing that breathes, but you shall devote them to complete
destruction, the Hittites and the Amorites, the Canaanites and the
Perizzites, the Hivites and the Jebusites, as the LORD your God has
commanded, that they may not teach you to do according to all their
abominable practices that they have done for their gods, and so you
sin against the LORD your God.

 “When you besiege a city for a long time, making war against it
in order to take it, you shall not destroy its trees by wielding an
axe against them. You may eat from them, but you shall not cut them
down. Are the trees in the field human, that they should be
besieged by you? Only the trees that you know are not trees for
food you may destroy and cut down, that you may build siegeworks
against the city that makes war with you, until it falls.
