Deuteronomy 20:2-4

Webster(i) 2 And it shall be when ye are come nigh to the battle, that the priest shall approach and speak to the people, 3 And shall say to them, Hear, O Israel, ye approach this day to 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.
