Deuteronomy 20:6-8

Amplified Bible

⁶ What man has planted a vineyard and has not put it to use [harvesting its fruit]? Let him go and return to his house, otherwise he might die in the battle and another man would begin to use its fruit. ⁷ And who is the man who is engaged (legally promised) to a woman and has not married her? Let him go and return to his house, otherwise he might die in the battle and another man would marry her.’ ⁸ Then the officers shall speak further to the soldiers and say, ‘Who is the man who is afraid and lacks courage? Let him go and return to his house, so that he does not cause his brothers’ courage to fail like his own.’
