Deuteronomy 20:3-5

Young's Literal Translation

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.

⁵ `And the authorities have spoken unto the people, saying, Who [is] the man that hath built a new house, and hath not dedicated it? -- let him go and turn back to his house, lest he die in battle, and another man dedicate it.
