John 6, 30-35

So they said, ‘What sign will you yourself do, the sight of which will make us believe in you? What work will you do? Our fathers ate manna in the desert; as scripture says: He gave them bread from heaven to eat.’  Jesus answered them: In all truth I tell you, it was not Moses who gave you the bread from heaven, it is my Father who gives you the bread from heaven, the true bread;  for the bread of Godheaven and gives life to the world.  ‘Sir,’ they said, ‘give us that bread always.’  Jesus answered them: I am the bread of life. No one who comes to me will ever hunger; no one who believes in me will is the bread which comes down from ever thirst.
