John 6:29-31

New Revised Standard Version, Anglicised Catholic Edition

²⁹ Jesus answered them, ‘This is the work of God, that you believe in him whom he has sent.’ ³⁰ So they said to him, ‘What sign are you going to give us then, so that we may see it and believe you? What work are you performing? ³¹ Our ancestors ate the manna in the wilderness; as it is written, “He gave them bread from heaven to eat.”’
