27Let your work not be for the food which comes to an end, but for the food which goes on for eternal life, which the Son of man will give to you, for on him has God the Father put his mark.
28Then they said to him, How may we do the works of God?
29Jesus, answering, said to them, This is to do the work of God: to have faith in him whom God has sent.
30So they said, What sign do you give us, so that we may see and have faith in you? What do you do?
31Our fathers had the manna in the waste land, as the Writings say, He gave them bread from heaven.
32Jesus then said to them, Truly I say to you, What Moses gave you was not the bread from heaven; it is my Father who gives you the true bread from heaven.
33The bread of God is the bread which comes down out of heaven and gives life to the world.
