Deuteronomy 20:5-9

5“The officers are to address the army, ‘Has any man built a new house and not dedicated it? Let him leave and return home. Otherwise, he may die in battle and another man dedicate it.

6Has any man planted a vineyard and not begun to enjoy its fruit? Let him leave and return home. Otherwise he may die in battle and another man enjoy its fruit.

7Has any man become engaged to a woman and not married her? Let him leave and return home. Otherwise he may die in battle and another man marry her.’

8The officers will continue to address the army and say, ‘Is there any man who is afraid or cowardly? Let him leave and return home, so that his brothers won’t lose heart as he did.’

9When the officers have finished addressing the army, they will appoint military commanders to lead it.
