Deuteronomy 29:3-5

New Century Version

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. ⁵ I led you through the desert for forty years, and during that time neither your clothes nor sandals wore out.
