'By Bread Alone' in the Bible

And he humbled thee, and suffered thee to hunger, and fed thee with the manna, which thou hadst not known, and which thy fathers knew not; that he might make thee know that man doth not live by bread alone, but by everything that goeth out of the mouth of Jehovah doth man live.

But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God.

And Jesus answered him, saying, It is written, That man shall not live by bread alone, but by every word of God.
