48 I am that bread of life.49 Your fathers ate manna in the wilderness, and are dead.50 This is the bread which cometh down from heaven, that a man may eat of it, and not die.51 I am the living bread which came down from heaven: if any man shall 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.
