Luke 11:3-13, Exodus 16:31 and:

This is the bread which cometh down from heaven, that a man may eat thereof, and not die.  I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever: and the bread that I will give is my flesh, which I will give for the life of the world. (John 6:50-51)

Our fathers did eat manna in the desert; as it is written, He gave them bread from heaven to eat. (John 6:31)
