Deuteronomy 29:2-20

​² 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, ³the great trials that your eyes saw, the signs, and those great wonders. ⁴But to this day the LORD has not given you a mind to understand, or eyes to see, or ears to hear.
