Numbers 10:29-33

29And Moses said to Hobab, the son of Raguel the Midianite, Moses’ father in law, We are journeying to the place of which the LORD said, I will give it to you: come thou with us, and we will do thee good: for the LORD hath spoken good concerning Israel. 30And he said to him, I will not go; but I will depart to my 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 wilt go with us, yea, it shall be, that what goodness the LORD shall do to us, the same will we do to 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 seek a resting place for them.
