Numbers 10:18

New Century Version

Then came the divisions from the camp of Reuben under their flag, and Elizur son of Shedeur was the commander.

See the chapter Copy

These are the names of the men who will help you: from the tribe of Reuben—Elizur son of Shedeur;

Shelumiel son of Zurishaddai was over the division of the tribe of Simeon.

When you loudly blow them again, the tribes camping on the south should move; the loud sound will tell them to move.
