Matthew 4:1-4

Then was Jesus led up of the Spirit into the wilderness to be tempted of the devil. And when he had fasted forty days and forty nights, he afterward hungered. And the tempter came and said unto him, If thou art the Son of God, command that these stones become bread. 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.
