“On the last day, that great day of the feast, Jesus stood and cried out, saying, ‘If anyone thirsts, let him come to Me and drink. He who believes in Me, as the Scripture has said, out of his heart will flow rivers of living water.’ But this He spoke concerning the Spirit, whom those believing in Him would receive; for the Holy Spirit was not yet given, because Jesus was not yet glorified.” John 7:37-39.
“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.
“Then Jesus said to them, ‘Most assuredly, I say to you, Moses did not give you the bread from Heaven, but My Father gives you the true bread from heaven. For the bread of God is He who comes down from heaven and gives life to the world.’ Then they said to Him, ‘Lord, give us this bread always.’” John 6:32-34.
