Deuteronomy 29:3-5

Amplified Bible

³ the great trials [of Pharaoh] which your eyes have seen, the signs and those great wonders. ⁴ Yet to this day the Lord has not given you a heart and mind to understand, nor eyes to see, nor ears to hear. ⁵ I have led you in the wilderness forty years; your clothes have not worn out on you, and your sandals have not worn out on your feet.
