Numbers 10:29-34

²⁹And Moses said unto Hobab, the son of Raguel the Midianite, Moses’ father in law, We are journeying unto the place of which the LORD said, I will give it you: come thou with us, and we will do thee good: for the LORD hath spoken good concerning Israel.

³⁰And he said unto him, I will not go; but I will depart to mine own land, and to my kindred.

³¹And he said, Leave us not, I pray thee; forasmuch as thou knowest how we are to encamp in the wilderness, and thou mayest be to us instead of eyes.

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

³³And they departed from the mount of the LORD three days’ journey: and the ark of the covenant of the LORD went before them in the three days’ journey, to search out a resting place for them.

³⁴And the cloud of the LORD was upon them by day, when they went out of the camp.
