Numbers 10:32-34

³²And if you come with us, we will give you a part in whatever good the Lord does for us.

³³So 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;

³⁴And by day the cloud of the Lord went over them, when they went forward from the place where they had put up their tents.
