47 Amen, amen, I say to you, whoever believes has eternal life.
48 I am the bread of life.
49 Your ancestors ate the manna in the desert, but they died;
50 this is the bread that comes down from heaven so that one may eat it and not die.
51 I am the living bread that came down from heaven; whoever eats this bread will live forever; and the bread that I will give is my flesh for the life of the world.”
52 The Jews quarreled among themselves, saying, “How can this man give us [his] flesh to eat?”
53 Jesus said to them, “Amen, amen, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you do not have life within you.
