Deuteronomy - Chapter 29

Now Moses called 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 which your eyes have seen, the signs, and those great wonders. Yet the Lord has not given you a heart to perceive and eyes to see and ears to hear, to this very day."

This can be contrasted with the words of Jesus to his disciples, in Matthew 13:

"But blessed are your eyes for they see, and your ears for they hear; for assuredly, I say to you that many prophets and righteous men desired to see what you see, and did not see it, and to hear what you hear, and did not hear it."
