Jesus said to them, "I am the bread of life. He who comes to me will not be hungry, and he who believes in me will never be thirsty.
They said therefore unto him, What sign will you show us then, that we might see, and believe you? what do you work? Our fathers did eat manna in the desert; as it is written, He gave them bread from heaven to eat. Then Jesus said unto them, Verily, verily, I say unto you, Moses gave you not that bread from heaven; but my Father gives you the true bread from heaven ( John 6:30-32 ).
