Matthew 4:1-4

1 Then Jesus was led up by the Spirit into the wilderness to be tempted by the devil.  2 When he had fasted forty days and forty nights, he was hungry afterward.  3 The tempter came and said to him, "If you are the Son of God, command that these stones become bread."

4 But he answered, “It is written, 'Man shall not live by bread alone, but by every word that proceeds out of the mouth of God.'”
