When the people saw that neither Jesus nor his disciples were there, they got into those boats and crossed to Capernaum to look for Jesus. When they found him on the other side, they said to him, 'Rabbi, when did you come here?'
Jesus answered: In all truth I tell you, you are looking for me not because you have seen the signs but because you had all the bread you wanted to eat. Do not work for food that goes bad, but work for food that endures for eternal life, which the Son of man will give you, for on him the Father, God himself, has set his seal.
Then they said to him, 'What must we do if we are to carry out God's work?' Jesus gave them this answer, 'This is carrying out God's work: you must believe in the one he has sent.'
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 God is the bread which comes down from heaven 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 ever thirst.
