Deuteronomy 20:5-9

5“Then the officers shall speak to the people, saying: ‘What man is there who has built a new house and has not dedicated it? Let him go and return to his house, lest he die in the battle and another man dedicate it.

6Also what man is there who has planted a vineyard and has not eaten of it? Let him go and return to his house, lest he die in the battle and another man eat of it.

7And what man is there who is betrothed to a woman and has not married her? Let him go and return to his house, lest he die in the battle and another man marry her.’

8“The officers shall speak further to the people, and say, ‘What man is there who is fearful and fainthearted? Let him go and return to his house, lest the heart of his brethren faint like his heart.’

9And so it shall be, when the officers have finished speaking to the people, that they shall make captains of the armies to lead the people.
