Deuteronomy 20:2-4

Darby Translation

² And it shall be, when ye approach unto the battle, that the priest shall draw near and speak unto the people,

³ and shall say unto them, Hear, Israel, ye are approaching this day unto battle against your enemies: let not your hearts faint, fear not, and do not tremble, neither be afraid of them;

⁴ for Jehovah your God is he that goeth with you, to fight for you against your enemies, to save you.
