48 I am the bread of life.
49 Your fathers did eat manna in the desert, and are dead.
50 This is the bread which cometh down from heaven; that if any man eat of it, he may not die.
51 I am the living bread which came down from heaven.
52 If any man eat of this bread, he shall live for ever; and the bread that I will give, is my flesh, for the life of the world.
53 The Jews therefore strove among themselves, saying: How can this man give us his flesh to eat?
54 Then Jesus said to them: Amen, amen I say unto you: Except you eat the flesh of the Son of man, and drink his blood, you shall not have life in you.
