Deuteronomy 20:8-10

Darby Translation

⁸ And the officers shall speak further unto the people, and shall say, What man is there that is timid and faint-hearted? let him go and return unto his house, lest his brethren's heart melt as well as his heart.

⁹ And it shall be, when the officers have ended speaking unto the people, that they shall place captains of the hosts at the head of the people.

¹⁰ When thou approachest unto a city to fight against it, thou shalt proclaim peace unto it.
