If G’d had nonetheless chosen to lead them on this route, it had been to shorten the distance they would have to travel so that they could get to their destination before their tendency to quarrel, etc., would result in major sins. Nonetheless, G’d’s efforts in this respect had not proven to be sufficient; they had sinned on numerous occasions at locations Moses recalls by name.

ונלך את כל המדבר הגדול, “we went through this great desert.” This refers to the wanderings during the eleven days of which Moses spoke earlier. והנורא ההוא, “and that awesome one.” [This is a reference to the dangerous reptiles inhabited by this desert;] there were snakes as large as beams and scorpions the size of bows.
