49Your fathers did eat manna in the wilderness, and are dead.
50This is the bread which cometh down from heaven, that a man may eat thereof, and not die.
51I 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.
52The Jews therefore strove amongst themselves, saying, How can this man give us his flesh to eat?
