Deuteronomy 29:2-6

Moses called all Israel together and said, You’ve seen with your own eyes everything that GOD did in Egypt to Pharaoh and his servants, and to the land itself—the massive trials to which you were eyewitnesses, the great signs and miracle-wonders. But GOD didn’t give you an understanding heart or perceptive eyes or attentive ears until right now, this very day. I took you through the wilderness for forty years and through all that time the clothes on your backs didn’t wear out, the sandals on your feet didn’t wear out, and you lived well without bread and wine and beer, proving to you that I am in fact GOD, your God.
