Deuteronomy 29:2-6

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, to all his servants, and to all his land; the great trials [of Pharaoh] which your eyes have seen, the signs and those great wonders. Yet to this day the LORD has not given you a heart and mind to understand, nor eyes to see, nor ears to hear. I have led you in the wilderness forty years; 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 strong drink, so that you might know that I am the LORD your God [on whom you must depend].
