Joshua 4:11-13

Young's Literal Translation

¹¹ And it cometh to pass when all the people have completed to pass over, that the ark of Jehovah passeth over, and the priests, in the presence of the people;

¹² and the sons of Reuben, and the sons of Gad, and the half of the tribe of Manasseh, pass over, by fifties, before the sons of Israel, as Moses had spoken unto them;

¹³ about forty thousand, armed ones of the host, passed over before Jehovah for battle, unto the plains of Jericho.
