Deuteronomy 29:2-4

New Century Version

² Moses called all the Israelites together and said to them:

You have seen everything the Lord did before your own eyes to the king of Egypt and to the king’s leaders and to the whole country. ³ With your own eyes you saw the great troubles, signs, and miracles. ⁴ But to this day the Lord has not given you a mind that understands; you don’t really understand what you see with your eyes or hear with your ears.
