Deuteronomy 29:2-4

And Moses called unto all Israel, and said unto them, Ye have seen all that Jehovah did before your eyes in the land of Egypt unto Pharaoh, and unto all his servants, and unto all his land; the great trials which thine eyes saw, the signs, and those great wonders: but Jehovah hath not given you a heart to know, and eyes to see, and ears to hear, unto this day.
