John 6:50-53

⁵⁰This is the bread which is coming down from heaven, that one may eat of it and not die.

⁵¹I am the living bread which came down from heaven; if any one eat of my bread, he will live for ever. Yea, and the bread which I will give for the life of the world is my flesh.

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

⁵³Jesus therefore said to them, Truly, truly do I say to you, Unless ye eat the flesh of the Son of man and drink his blood, ye have no life in you.
