28 Therefore, they said to him, "What should we do, so that we may labor in the works of God?"
29 Jesus responded and said to them, "This is the work of God, that you believe in him whom he sent."
30 And so they said to him: "Then what sign will you do, so that we may see it and believe in you? What will you work?
31 Our fathers ate manna in the desert, just as it has been written, 'He gave them bread from heaven to eat.' "
32 Therefore, Jesus said to them: "Amen, amen, I say to you, Moses did not give you bread from heaven, but my Father gives you the true bread from heaven.
33 For the bread of God is he who descends from heaven and gives life to the world."
34 And so they said to him, "Lord, give us this bread always."
