John 6:51-53 Holman Christian Standard Bible (HCSB)
51 I am the living bread that came down from heaven. If anyone eats of this bread he will live forever. The bread that I will give for the life of the world is My flesh.”
52 At that, the Jews argued among themselves, “How can this man give us His flesh to eat?”
53 So Jesus said to them, “I assure you: Unless you eat the flesh of the Son of Man and drink His blood, you do not have life in yourselves.
