Numbers 10:24

And over the host of the tribe of the children of Benjamin was Abidan the son of Gideoni.

The verse records a single appointment within the organized advance of Israel, when the nation broke camp and moved forward as a disciplined host rather than a crowd. Each tribe marched under its own distinct standard, keeping the station assigned to it in the camp and on the road. Place and order were fixed for every division, so each knew where to belong and when to move in the procession.
