Deuteronomy 29:1-4

The LORD commanded Moses to make an agreement with the Israelites in Moab in addition to the agreement he had made with them at Mount Sinai. These are the words of that agreement. 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. With your own eyes you saw the great troubles, signs, and miracles. 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.
