John 6:33, 48, 51, 58

For the bread of God is he which cometh down from heaven, and giveth life unto the world.

I am that bread of life.

I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever: and the bread that I will give is my flesh, which I will give for the life of the world.

This is that bread which came down from heaven: not as your fathers did eat manna, and are dead: he that eateth of this bread shall live for ever.
