Jesus answered him, saying, "It is written, 'Man shall not live by bread alone, but by every word of God.'"

 4:31-37 Jesus came down to Capernaum, a town in Galilee, and he was teaching them on the Sabbath day; and they were astonished at his teaching because his speech was with authority. There was in the synagogue a man who had a spirit of an unclean demon and he cried out with a loud voice, "What have we to do with you, Jesus of Nazareth? Have you come to destroy us? I know who you are--the Holy One of God." So Jesus rebuked it. "Be muzzled," he said, "and come out of him." And after the demon had thrown him into the midst of them, it came out of him and it did him no harm. Astonishment fell on them all and they kept saying to each other, "What word is this? because he gives orders to unclean spirits with authority and with power and they come out." And the story of him went out to every place in the surrounding district.
