Deuteronomy 29:1-6

1 These are the terms of the covenant that the Lord commanded Moses to make with the people of Israel in the land of Moab; all this was in addition to the covenant which the Lord had made with them at Mount Sinai.
2 Moses called together all the people of Israel and said to them, "You saw for yourselves what the Lord did to the king of Egypt, to his officials, and to his entire country.
3 You saw the terrible plagues, the miracles, and the great wonders that the Lord performed.
4 But to this very day he has not let you understand what you have experienced.
5 For forty years the Lord led you through the desert, and your clothes and sandals never wore out.
6 You did not have bread to eat or wine or beer to drink, but the Lord provided for your needs in order to teach you that he is your God.
