10:29-32 Moses invites his kindred to go to Canaan. Those that are bound for the heavenly Canaan, should ask and encourage their friends to go with them: we shall have none the less of the joys of heaven, for others coming to share with us. It is good having fellowship with those who have fellowship with God. But the things of this world, which are seen, draw strongly from the pursuit of the things of the other world, which are not seen. Moses urges that Hobab might be serviceable to them. Not to show where they must encamp, nor what way they must march, the cloud was to direct that; but to show the conveniences of the place they marched through, and encamped in. It well consists with our trust in God's providence, to use the help of our friends.

31. Leave us not, I pray thee … and thou mayest be to us instead of eyes—The earnest importunity of Moses to secure the attendance of this man, when he enjoyed the benefit of the directing cloud, has surprised many. But it should be recollected that the guidance of the cloud, though it showed the general route to be taken through the trackless desert, would not be so special and minute as to point out the places where pasture, shade, and water were to be obtained and which were often hid in obscure spots by the shifting sands. Besides, several detachments were sent off from the main body; the services of Hobab, not as a single Arab, but as a prince of a powerful clan, would have been exceedingly useful.
