Numbers 10:31

Thou mayest be to us instead of eyes - But what need had they of Hobab, when they had the pillar and fire continually to point out their way? Answer: The cloud directed their general journeys, but not their particular excursions. Parties took several journeys while the grand army lay still. (See Numbers 13, 20, 31, 32, etc). They therefore needed such a person as Hobab, who was well acquainted with the desert, to direct these particular excursions; to point them out watering places, and places where they might meet with fuel, etc., etc. What man cannot, under the direction of God's providence, do for himself, God will do in the way of especial mercy. He could have directed them to the fountains and to the places of fuel, but Hobab can do this, therefore let Hobab be employed; and let Hobab know for his encouragement that, while he is serving others in the way of God's providence, he is securing his own best interests. On these grounds Hobab should be invited, and for this reason Hobab should go. Man cannot do God's work; and God will not do the work which he has qualified and commanded man to perform. Thus then the Lord is ever seen, even while he is helping man by man. See some valuable observations on this subject in Harmer, vol. ii., 286. Instead of, And thou mayest be to us instead of eyes, the Septuagint translate the passage thus: Και εσῃ εν ἡμιν πρεσβυτης, And thou shalt be an elder among us. But Moses probably refers to Hobab's accurate knowledge of the wilderness, and to the assistance he could give them as a guide.

Thou mayest be to us instead of eyes - A proverbial expression still in use in the East. Hobab would indicate the spots where water, fuel, and pasture might be found, or warn them of the dangers from hurricanes, and point out localities infested by robbers.

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, 18:19 - 27. And it is probable, this was the wise son of a wise father.
