Deuteronomy 20:5-7

5The officers should tell the troops, “If you have built a new house but not dedicated it, you may go home. Otherwise, you might die in battle, and someone else will dedicate it.

6If you have planted a vineyard and not enjoyed the grapes, you may go home. Otherwise, you might die in battle, and someone else will enjoy the grapes.

7If you are engaged to a woman but have not married her, you may go home. Otherwise, you might die in battle, and someone else will marry her.”
