Deuteronomy 29:4

2Moses called to all Israel, and said to them: Your eyes have seen all that the LORD did in the land of Egypt to Pharaoh, and to all his servants, and to all his land;

3the great trials which your eyes saw, the signs, and those great wonders.

4But the LORD has not given you a heart to know, eyes to see, and ears to hear, to this day.

5I have led you forty years in the wilderness. Your clothes have not grown old on you, and your sandals have not grown old on your feet.

6You have not eaten bread, neither have you drunk wine or strong drink, that you may know that I am the LORD your God.
