Numbers 10:32-34

³²And it shall be that if thou wilt go with us, with the good by which the Lord shall do us good, will we do good to thee.

³³And from the mountain on which the glory of the Lord had been revealed they went forward, journeying three days; and the ark of the Lord’s covenant went before them, three days’ journey, to provide for them a place of encampment.

³⁴And the Cloud of Glory of the Lord overspread them by day as they went forth from their encampments.
