John 6: 24-35
24 When therefore the multitude saw that Jesus was not there, nor his disciples, they took shipping, and came to Capharnaum, seeking for Jesus.
25 And when they had found him on the other side of the sea, they said to him: Rabbi, when camest thou hither?
26 Jesus answered them, and said: Amen, amen I say to you, you seek me, not because you have seen miracles, but because you did eat of the loaves, and were filled.
27 Labour not for the meat which perisheth, but for that which endureth unto life everlasting, which the Son of man will give you. For him hath God, the Father, sealed.
28 They said therefore unto him: What shall we do, that we may work the works of God?
29 Jesus answered, and said to them: This is the work of God, that you believe in him whom he hath sent.
30 They said therefore to him: What sign therefore dost thou shew, that we may see, and may believe thee? What dost thou work?
31 Our fathers did eat manna in the desert, as it is written: He gave them bread from heaven to eat.
32 Then Jesus said to them: Amen, amen I say to you; Moses gave you not bread from heaven, but my Father giveth you the true bread from heaven.
33 For the bread of God is that which cometh down from heaven, and giveth life to the world.
34 They said therefore unto him: Lord, give us always this bread.
35 And Jesus said to them: I am the bread of life: he that cometh to me shall not hunger: and he that believeth in me shall never thirst.
