“I am the living bread which came down from heaven. If anyone eats of this bread, he will live forever; and the bread that I shall give is My flesh, which I shall give for the life of the world.” The Jews therefore quarreled among themselves, saying, ‘How can this Man give us His flesh to eat?’ Then Jesus said to them, “Most assuredly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in you.” John 6:51-53.
“I am the bread of life. Your fathers ate the manna in the wilderness, and are dead. This is the bread which comes down from heaven, that one may eat of it and not die.” John 6:48-50.
“The Jews then murmured against Him, because He said, ‘I am the bread which came down from heaven.’ And they said, ‘Is not this Jesus, the son of Joseph, whose father and mother we know? How is it then that He says, “I have come down from heaven”?’” John 6:41-42.
