Encouragement for Battle

Deuteronomy 20:1-4

1  When thou go out to battle against thine enemies, and see 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 go with you, to fight for you against your enemies, to save you.
