John 6:56-59

56Whoever eats my flesh and drinks my blood remains in me, and I in them. 57Just as the living Father sent me and I live because of the Father, so the one who feeds on me will live because of me. 58This is the bread that came down from heaven. Your ancestors ate manna and died, but whoever feeds on this bread will live forever.”

59He said this while teaching in the synagogue in Capernaum.
