Numbers 10:28-34

²⁸These were the settings forward of the children of Israel according to their hosts: so did they set forward.

²⁹And Moses said to Hobab, the son of Reuel the Midianite, Moses' father-in-law, We are journeying to the place of which Jehovah said, I will give it unto you: come with us, and we will do thee good; for Jehovah has spoken good concerning Israel.

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

³¹And he said, Leave me not, I pray thee, because thou knowest where we are to encamp in the wilderness, and thou wilt be to us for eyes.

³²And it shall be, if thou come with us, that whatever good Jehovah doeth unto us, so will we do to thee.

³³And they set forward from the mountain of Jehovah and went three days' journey; and the ark of the covenant of Jehovah went before them in the three days' journey, to search out a resting-place for them.

³⁴And the cloud of Jehovah was over them by day when they set forward out of the camp.
