Deuteronomy 29:2-6

Now Moses called all Israel and said to them: “You have seen all that the LORD did before your eyes in the land of Egypt, to Pharaoh and to all his servants and to all his land— the great trials which your eyes have seen, the signs, and those great wonders. Yet the LORD has not given you a heart to perceive and eyes to see and ears to hear, to this very day. And I have led you forty years in the wilderness. Your clothes have not worn out on you, and your sandals have not worn out on your feet. You have not eaten bread, nor have you drunk wine or similar drink, that you may know that I am the LORD your God.
