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.
