:confused: what does the bread of life mean?

To the Israelites, the bread of life was Mannan. In The Gospel of John Jesus says He is the Bread of Life.

John 6: 49-51. "Your fathers ate the manna in the wilderness, and they died.
50"This is the bread which 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, he will live forever; and the bread also which I will give for the life of the world is My flesh."

Bread is a staple, thus it gives life. Jesus is likened to the bread of life because he gives life
