John 6:51 ASV

⁴⁹  Your fathers ate the manna in the wilderness, and they died.

⁵⁰  This is the bread which cometh down out of heaven, that a man may eat thereof, and not die.

⁵¹  I am the living bread which came down out of heaven: if any man eat of this bread, he shall live for ever: yea and the bread which I will give is my flesh, for the life of the world.

⁵²  The Jews therefore strove one with another, saying, How can this man give us his flesh to eat?

⁵³  Jesus therefore said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man and drink his blood, ye have not life in yourselves.
