Numbers 10:28-32

²⁸In this order were the journeyings of the children of Israel according to their armies, when they set forward.

²⁹And Moses said unto Chobab, the son of Reuel the Midianite, the father-in-law of Moses, We are journeying unto the place of which the Lord hath said, This will I give unto you: come thou with us, and we will do thee good; for the Lord hath spoken to bring good upon Israel.

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

³¹And he said, Do not, I pray thee, leave us; since thou didst find out the places where we were to encamp in the wilderness, and thou hast been to us instead of eyes.

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