They went forward for the first time on their journey as the Lord had given orders by the hand of Moses.
Numbers 10:13
Num 10:33 So they went forward three days’ journey from the mountain of the Lord; and the ark of the Lord’s agreement went three days’ journey before them, looking for a resting-place for them;
Num 10:34 And by day the cloud of the Lord went over them, when they went forward from the place where they had put up their tents.
