Then Jesus was led by the Spirit into the desert to be tempted by the devil. He fasted for forty days and forty nights, and afterwards he was hungry. The tempter approached and said to him, “If you are the Son of God, command that these stones become loaves of bread.” He said in reply, “It is written: ‘One does not live by bread alone, but by every word that comes forth from the mouth of God.’” (Matthew 4:1-4)
