Had he not provided us with our needs in the wilderness…. Providing food to the world is one of the things that God does not only for Israel but for the entire world. So, on the one hand it would have been fine had this particular miracle not been mention. On the other hand providing food for an entire nation in the wilderness was truly miraculous. By providing for the people in the wilderness God taught the people to depend on God and thereby helped them to become more worthy of receiving the Torah at Sinai. Forcing them to go to the wilderness was yet another act of purification that helped them prepare for the events at Mount Sinai.
