Numbers 10:32-34

³²And if thou comest with us, we will give thee what is the best of the riches which the Lord shall deliver to us.

³³So they marched from the mount of the Lord three days’ journey, and the ark of the covenant of the Lord went before them, for three days providing a place for the camp.

³⁴The cloud also of the Lord was over them by day when they marched.
