1 When thou goest out to battle against thine enemies, and seest horses, and chariots, and a people more than thou, be not afraid of them; for the Lord thy God is with thee, which brought thee up out of the land of Egypt.
2 And it shall be, when ye are come nigh unto the battle, that the priest shall approach and speak unto the people,
3 And shall say unto them, Hear, O Israel, ye approach this day unto battle against your enemies; let not your hearts faint, fear not, and do not tremble, neither be ye terrified because of them;
4 For the Lord your God is he that goeth with you, to fight for you against your enemies, to save you.
5 And the officers shall speak unto the people, saying, What man is there that hath built a new house, and hath not dedicated it? let him go and return to his house, lest he die in the battle, and another man dedicate it.
6 And what man is he that hath planted a vineyard, and hath 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.
7 And what man is there that hath betrothed a wife, and hath not taken her? let him go and return unto his house, lest he die in the battle, and another man take her.
8 And the officers shall speak further unto the people, and they shall say, What man is there that is fearful and faint-hearted? let him go and return unto his house, lest his brethren's heart faint as well as his heart.
9 And it shall be, when the officers have made an end of speaking unto the people, that they shall make captains of the armies to lead the people.
