John 6:50-52

Amplified Bible

⁵⁰ This is the Bread that comes down out of heaven, so that one may eat of it and not die. ⁵¹ I am the Living Bread that came down out of heaven. If anyone eats of this Bread [believes in Me, accepts Me as Savior], he will live forever. And the Bread that I will give for the life of the world is My flesh (body).”

⁵² Then the Jews began to argue with one another, saying, “How can this man give us His flesh to eat?”
