Numbers 10:29-34

²⁹And Moses saith to Hobab son of Raguel the Midianite, father-in-law of Moses, 'We are journeying unto the place of which Jehovah hath said, I give it to you; go with us, and we have done good to thee; for Jehovah hath spoken good concerning Israel.'

³⁰And he saith unto him, 'I do not go; but unto my land and unto my kindred do I go.'

³¹And he saith, 'I pray thee, forsake us not, because thou hast known our encamping in the wilderness, and thou hast been to us for eyes;

³²and it hath come to pass when thou goest with us, yea, it hath come to pass — that good which Jehovah doth kindly with us — it we have done kindly to thee.'

³³And they journey from the mount of Jehovah a journey of three days; and the ark of the covenant of Jehovah is journeying before them the journey of three days, to spy out for them a resting-place;

³⁴and the cloud of Jehovah is on them by day, in their journeying from the camp.
