Numbers 10:31

Thou mayest be to us instead of eyes — To direct and guide us: for though the cloud determined them to a general place, yet many particulars might be unknown to Moses, wherein Hobab, having long lived in those parts, might be able to advise him, as concerning the conveniences of water for their cattle, concerning the safety or danger of the several parts, by reason of serpents or wild — beasts, or enemies, in the parts adjoining to them, that so they might guard themselves better against them. Or, this is to be understood of his directing them not so much in their way. as about great and difficult matters, wherein the counsel he had from God did not exclude the advice of men, as we see in Hobab's father Jethro, Exodus 18:19. And it is probable, this was the wise son of a wise father.
