Numbers 10:28-32

²⁸These are the armies of the children of Israel; and they set forward with their forces.

²⁹And Moses said to Hobab the son of Reuel the Midianite, the father-in-law of Moses, We are going forward to the place concerning which the Lord said, This will I give to you: Come with us, and we will do thee good, for the Lord has spoken good concerning Israel.

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

³¹And he said, Leave us not, because thou hast been with us in the wilderness, and thou shalt be an elder among us.

³²And it shall come to pass if thou wilt go with us, it shall even come to pass that in whatsoever things the Lord shall do us good, we will also do thee good.
