Deuteronomy 8:3-4

3And He humbled you and let you go hungry, and fed you with the manna which you did not know, nor did your fathers know, in order to make you 1understand that 2man shall not live on bread alone, but man shall live on everything that comes out of the mouth of the Lord.

43Your clothing did not wear out on you, nor did your foot swell these forty years.
