Deuteronomy 20:5-9

5Then the officers shall speak to the people, saying, 'Is there any man who has built a new house and has not dedicated it? Let him go back to his house, lest he die in the battle and another man dedicate it.

6And is there any man who has planted a vineyard and has not enjoyed its fruit? Let him go back to his house, lest he die in the battle and another man enjoy its fruit.

7And is there any man who has betrothed a wife and has not taken her? Let him go back to his house, lest he die in the battle and another man take her.'

8And the officers shall speak further to the people, and say, 'Is there any man who is fearful and fainthearted? Let him go back to his house, lest he make the heart of his fellows melt like his own.'

9And when the officers have finished speaking to the people, then commanders shall be appointed at the head of the people.
