Deuteronomy 20:3 In-Context

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.
