Deuteronomy 20:5-7

The officers also shall speak to the people, saying, ‘Who is the man that has built a new house and has not dedicated it? Let him depart and return to his house, otherwise he might die in the battle and another man would dedicate it. Who is the man that has planted a vineyard and has not begun to use its fruit? Let him depart and return to his house, otherwise he might die in the battle and another man would begin to use its fruit. And who is the man that is engaged to a woman and has not married her? Let him depart and return to his house, otherwise he might die in the battle and another man would marry her.’
