American Standard Version And it shall be, when the officers have made an end of speaking unto the people, that they shall appoint captains of hosts at the head of the people.
Young's Literal Translation and it hath come to pass as the authorities finish to speak unto the people, that they have appointed princes of the hosts at the head of the people.
