[18] The flag of the camp of Reuben was next with Elizur son of Shedeur in command. Shelumiel son of Zurishaddai commanded the forces of the tribe of Simeon; Eliasaph son of Deuel commanded the forces of the tribe of Gad. Then the Kohathites left, carrying the holy things. By the time they arrived The Dwelling would be set up.
