Deuteronomy 20:2-4

Young's Literal Translation

² and it hath been, in your drawing near unto the battle, that the priest hath come nigh, and spoken unto the people,

³ and said unto them, Hear, Israel, ye are drawing near to-day to battle against your enemies, let not your hearts be tender, fear not, nor make haste, nor be terrified at their presence,

⁴ for Jehovah your God [is] He who is going with you, to fight for you with your enemies -- to save you.
