Jamieson, Fausset and Brown on Numbers 14:6

6. Joshua ... and Caleb, which were of them that searched the land, rent their clothes--The two honest spies testified their grief and horror, in the strongest manner, at the mutiny against Moses and the blasphemy against God; while at the same time they endeavored, by a truthful statement, to persuade the people of the ease with which they might obtain possession of so desirable a country, provided they did not, by their rebellion and ingratitude, provoke God to abandon them.
