Numbers 10:32-34

³²and when thou shalt come with us, whatever thing shall be best of the riches that the Lord shall give to us, we shall give to thee.

³³And therefore they went forth from the hill or mount of the Lord the way of three days; and the ark of the bond of peace of the Lord went before them, by those three days, and purveyed the places of their tents.

³⁴And the cloud of the Lord was upon, or over, them by day, when they went forth.
