Deuteronomy 29:2-6

Moses summoned all the Israelites and said to them, “You have seen with your own eyes everything the LORD did in the land of Egypt to Pharaoh and to all his servants and to his whole country— all the great tests of strength, the miraculous signs, and the amazing wonders. But to this day the LORD has not given you minds that understand, nor eyes that see, nor ears that hear! For forty years I led you through the wilderness, yet your clothes and sandals did not wear out. You ate no bread and drank no wine or other alcoholic drink, but he provided for you so you would know that he is the LORD your God.
