Numbers 2:10-16

10The tribe of Reuben must be on the south side of the Tent. They must have their flag with them, and they must put up their tents in groups. The leader of the tribe of Reuben is Elizur, the son of Shedeur.

11There will be 46,500 soldiers in his army.

12The tribe of Simeon will put up their tents on one side of Reuben's camp. The leader of the tribe of Simeon is Shelumiel, the son of Zurishaddai.

13There will be 59,300 soldiers in his army.

14The tribe of Gad will be on the other side of Reuben's camp. The leader of the tribe of Gad is Eliasaph, the son of Deuel.

15There will be 45,650 soldiers in his army.

16So there will be 151,450 soldiers in the three groups on Reuben's side of the camp. When the people travel, they will march second.
