Deuteronomy 20:5-15

5 Then the officers shall speak to the people, saying, 'What man is there that 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.
6 And what man is there that 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.
7 And what man is there that 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.'
8 And the officers shall speak further to the people, and say, 'What man is there that is fearful and fainthearted? Let him go back to his house, lest the heart of his fellows melt as his heart.'
9 And when the officers have made an end of speaking to the people, then commanders shall be appointed at the head of the people.
10 "When you draw near to a city to fight against it, offer terms of peace to it.
11 And if its answer to you is peace and it opens to you, then all the people who are found in it shall do forced labor for you and shall serve you.
12 But if it makes no peace with you, but makes war against you, then you shall besiege it;
13 and when the LORD your God gives it into your hand you shall put all its males to the sword,
14 but the women and the little ones, the cattle, and everything else in the city, all its spoil, you shall take as booty for yourselves; and you shall enjoy the spoil of your enemies, which the LORD your God has given you.
15 Thus you shall do to all the cities which are very far from you, which are not cities of the nations here.
