John 6:49-54
English Standard Version
Chapter 6
49Your fathers ate the manna in the wilderness, and they died. 50This is the bread that comes down from heaven, so that one may eat of it and not die. 51I am the living bread that came down from heaven. If anyone eats of this bread, he will live forever. And the bread that I will give for the life of the world is my flesh."
52The Jews then disputed among themselves, saying, "How can this man give us his flesh to eat?"
53So Jesus said to them, "Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you.
54Whoever feeds on my flesh and drinks my blood has eternal life, and I will raise him up on the last day.
