Judah's camp led the way — Nahshon son of Amminadab commanding Judah, Nethanel son of Zuar leading Issachar, Eliab son of Helon leading Zebulun.
Then the Gershonites and Merarites — the Levite families responsible for carrying the tabernacle's frame and coverings — took it all down and moved out.
Reuben's camp came next — Elizur son of Shedeur over Reuben, Shelumiel son of Zurishaddai over Simeon, Eliasaph son of Deuel over Gad.
Then the Kohathites set out, carrying the holy objects — the sacred vessels, the lampstand, the altars. And here's the detail that matters: the tabernacle was already set up and waiting before they arrived.
Ephraim's camp followed — Elishama son of Ammihud over Ephraim, Gamaliel son of Pedahzur over Manasseh, Abidan son of Gideoni over Benjamin.
And finally, Dan's camp — the rear guard for the entire nation — Ahiezer son of Ammishaddai over Dan, Pagiel son of Ochran over Asher, Ahira son of Enan over Naphtali. That was the order of march. That was how Israel moved.
