My servant Caleb, inasmuch as there was another spirit with him…which "other" spirit rested within Caleb? Rashi explains that his mind and speech were not aligned, each one had its own spirit. In his mind he thought the land could be conquered, but in his speech he agreed with the majority of spies who were against entering the land. While this sort of deceptive behavior is not usually acceptable, Rashi points out that Caleb used it for good. Because the spies believed that he agreed with them, only he was able to quiet them: Caleb silenced the people around Moses and said, "We will surely go up…And therefore the Torah praised him for his ability to maintain "another spirit."
