Deuteronomy 20:5-7

“Then the officers of the army must address the troops and say, ‘Has anyone here just built a new house but not yet dedicated it? If so, you may go home! You might be killed in the battle, and someone else would dedicate your house. Has anyone here just planted a vineyard but not yet eaten any of its fruit? If so, you may go home! You might die in battle, and someone else would eat the first fruit. Has anyone here just become engaged to a woman but not yet married her? Well, you may go home and get married! You might die in the battle, and someone else would marry her.’
