R. Eliezer says: They journeyed by word of the L–rd. For in two or three places we find that they journeyed by word of the L–rd; and here, too, they journeyed by word of the L–rd. And why is it written "And Moses made Israel journey? To apprise us of the eminence of Israel. That when Moses told them "Arise and journey," they did not counter "How can we venture into the desert with nothing to eat on the way?", but they believed and they followed Moses. And of them it is written in the Tradition (Jeremiah 2:2) "Go and proclaim in the ears of Jerusalem … I have remembered for you the lovingkindness of your youth … your going after Me in the desert, in an unknown land."
