1When you go forth to battle against your enemies, and see horses, chariots, and a people more than you, 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. 2It shall be, when you draw near to the battle, that the priest shall approach and speak to the people, 3and shall tell them, "Hear, Israel, you draw near this day to battle against your enemies: do not let your heart faint; do not be afraid, nor tremble, neither be scared of them; 4for the LORD your God is he who goes with you, to fight for you against your enemies, to save you." 5The officers shall speak to the people, saying, "What man is there who has built a new house, and has not dedicated it? Let him go and return to his house, lest he die in the battle, and another man dedicate it. 6What man is there who has planted a vineyard, and has not used its fruit? Let him go and return to his house, lest he die in the battle, and another man use its fruit. 7What man is there who has pledged to be married a wife, and has not taken her? Let him go and return to his house, lest he die in the battle, and another man take her." 8The officers shall speak further to the people, and they shall say, "What man is there who is fearful and fainthearted? Let him go and return to his house, lest his brother's heart melt as his heart." 9It shall be, when the officers have made an end of speaking to the people, that they shall appoint captains of armies at the head of the people.

10When you draw near to a city to fight against it, then proclaim peace to it. 11It shall be, if it makes you answer of peace, and opens to you, then it shall be, that all the people who are found in it shall become tributary to you, and shall serve you. 12If it will make no peace with you, but will make war against you, then you shall besiege it: 13and when the LORD your God delivers it into your hand, you shall strike every male of it with the edge of the sword: 14but the women, and the little ones, and the livestock, and all that is in the city, even all its spoil, you shall take for a prey to yourself; and you shall eat the spoil of your enemies, which the LORD your God has given you. 15Thus you shall do to all the cities which are very far off from you, which are not of the cities of these nations. 16But of the cities of these peoples, that the LORD your God gives you for an inheritance, you shall save alive nothing that breathes; 17but you shall utterly destroy them: the Hethite, and the Amorite, the Canaanite, and the Perizzite, and the Hivite, and the Jebusite; as the LORD your God has commanded you; 18that they not teach you to do after all their abominations, which they have done to their gods; so would you sin against the LORD your God.

19When you shall besiege a city a long time, in making war against it to take it, you shall not destroy its trees by wielding an axe against them; for you may eat of them, and you shall not cut them down; for is the tree of the field man, that it should be besieged of you? 20Only the trees of which you know that they are not trees for food, you shall destroy and cut them down; and you shall build siege works against the city that makes war with you, until it fall.
