Numbers 7:11

יקריבו את קרבנם לחנכת המזבח THEY SHALL OFFER THEIR OFFERING, [EACH PRINCE ON HIS DAY] FOR THE DEDICATING OF THE ALTAR — but Moses did not yet know how they were to bring their offerings — whether according to the order of their birth (i.e. according to the order in which the sons of Jacob after whom the tribes were named were born, in which case the prince of the tribe of Reuben would have offered first), or according to the order in which they moved off on the journeys, (when Judah would be the first), until he was told by the mouth of the Holy One, blessed be He: “according to the order on the journeys shall they offer” — yet each prince on his day (and not three together as they actually journeyed) (cf. Sifrei Bamidbar 47).

And the Lord said to Moshe, They shall offer their offering, each prince on his day, for the dedicating of the altar.
