Deuteronomy 29:2-6 ESV

And Moses summoned 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 that your eyes saw, the signs, and those great wonders. But to this day the LORD has not given you a heart to understand or eyes to see or ears to hear. I have led you forty years in the wilderness. Your clothes have not worn out on you, and your sandals have not worn off your feet. You have not eaten bread, and you have not drunk wine or strong drink, that you may know that I am the LORD your God.
