Deuteronomy 20:5-9

5The officers also shall speak to the people, saying, ‘Who is the man that has built a new house and has not 1dedicated it? Let him depart and return to his house, otherwise he might die in the battle and another man would dedicate it. 6Who is the man that has planted a vineyard and has not 2begun to use its fruit? Let him depart and return to his house, otherwise he might die in the battle and another man 3would begin to use its fruit. 74And who is the man that is engaged to a woman and has not 5married her? Let him depart and return to his house, otherwise he might die in the battle and another man 6would marry her.’ 8Then the officers shall speak further to the people and say, ‘7Who is the man that is afraid and fainthearted? Let him depart and return to his house, so that 8he might not make his brothers’ hearts melt like his heart.’ 9When the officers have finished speaking to the people, they shall appoint commanders of armies at the head of the people.
