Deuteronomy 20:5-7

5“The officers are to speak to the troops saying, ‘What man has built a new house but has not dedicated it? Let him go back to his house—otherwise he might die in the battle and another man would dedicate it.

6What man has planted a vineyard but has not put it to use? Let him go back to his house—otherwise he might die in the battle and another man would begin to use it.

7What man has become engaged to a woman but has not married her? Let him go back to his house—otherwise he might die in the battle and another man would marry her.’
