Not to get ahead of ourselves, but, it was forty years of Manna only because of their disobedience and lack of trust. Since the chapter began with God wanting to prove whether they would obey or no, we should know that almost immediately from outset onward the answer was no. For the manna obedience was somewhat locked in, it would spoil overnight and not grow on Sabbath. For the many other things God was doing the obedience was more voluntary. You have to remember also that these people were in a desert isolated from foreign influences and still had these disobedient tendencies. Is our nature any different? Where do we stand in our proving yet today?
