LXX Num 2:17

Καὶ ἀρθήσεται ἡ σκηνὴ τοῦ μαρτυρίου, καὶ ἡ παρεμβολὴ τῶν Λευειτῶν μέσον τῶν παρεμβολῶν· ὡς καὶ παρεμβάλλουσιν, οὕτως καὶ ἐξαροῦσιν ἕκαστος ἐχόμενος καθ’ ἡγεμονίαν.

In the middle of the camps, the Tent of Meeting is to travel with the camp of the Levites. They are to set out in the order they encamped, each in his own place under his standard.
