NUMBERS 10:32-34

³²And it shall be, if thou go with us, yea, it shall be, that what good soever the LORD shall do unto us, the same will we do unto thee.

³³And they set forward from the mount of the LORD three days’ journey; and the ark of the covenant of the LORD went before them three days’ journey, to seek out a resting place for them.

³⁴And the cloud of the LORD was over them by day, when they set forward from the camp.
