“The Holy Spirit led Jesus into the desert, so that the devil could test him. After Jesus had gone without eating for forty days and nights, he was very hungry. Then the devil came to him and said, “If you are God’s Son, tell these stones to turn into bread.”
Jesus answered, "The Scriptures say: ‘No one can live only on food. People need every word that God has spoken.’ "
from Chapter 4 in the Book of Matthew in The Holy Bible
