Deuteronomy 20:2-4

TKJU(i) 2 And it shall be, when you have come near to the battle, that the priest shall approach and speak to the people, 3 and shall say to them, Hear, O Israel, you approach this day to battle against your enemies: Let not your hearts faint, fear not, and do not tremble, neither be you terrified because of them; 4 for the LORD your God is he that goes with you, to fight for you against your enemies, to save you.
