Deuteronomy 20:5-7
5 The officers shall say to the army: “Has anyone built a new house and not dedicated it? Let him go home, or he may die in battle and someone else may dedicate it.
6 Has anyone planted a vineyard and not begun to enjoy it? Let him go home, or he may die in battle and someone else enjoy it.
7 Has anyone become pledged to a woman and not married her? Let him go home, or he may die in battle and someone else marry her.”
