Deuteronomy 8:3-4

LEB(i) 3 And he humbled you and let you go hungry, and then he fed you with that which you did not know nor did your ancestors* know, in order to make you know that not by bread alone but by all that goes out* of the mouth of Yahweh humankind shall live. 4 Your clothing did not wear out on you,* and your feet did not swell during these forty years.
