Thematic Bible: Exhorted before battle

When you go out to battle against your enemies, and see horses, and chariots, and a people more than you, be not afraid of them: for the LORD your God is with you, who brought you up out of the land of Egypt. And it shall be, when you are come near unto the battle, that the priest shall approach and speak unto the people, And shall say unto them, Hear, O Israel, you approach this day unto battle against your enemies: let not your hearts faint, fear not, and do not tremble, neither be you terrified because of them; read more.
For the LORD your God is he that goes with you, to fight for you against your enemies, to save you. And the officers shall speak unto the people, saying, What man is there that 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. And what man is he that has planted a vineyard, and has not yet eaten of it? let him also go and return unto his house, lest he die in the battle, and another man eat of it. And what man is there that has betrothed a wife, and has not taken her? let him go and return unto his house, lest he die in the battle, and another man take her. And the officers shall speak further unto the people, and they shall say, What man is there that is fearful and fainthearted? let him go and return unto his house, lest his brethren's heart faint as well as his heart. And it shall be, when the officers have finished speaking unto the people, that they shall make captains of the armies to lead the people.
