"They said therefore unto him,What sign shewest thou then,that we may see,and believe thee?what dost thou 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 giveth you the true bread from heaven.
For the bread of God is he which cometh down from heaven,and giveth life unto the world."
John 6:30-33
