Jesus Christ Spoke of Manna, Revealing its True Significance :

"Our fathers ate the manna in the wilderness; as it is written, 'He gave them bread from heaven to eat.'" Jesus then said to them, "Truly, truly, I say to you, it was not Moses who gave you the bread from heaven; My Father gives you the true bread from heaven. For the bread of God is that which comes down from heaven, and gives life to the world." (John 6:31-33)

AND

"I am the bread of life. Your fathers ate the manna in the wilderness, and they died. This is the bread which comes down from heaven, that a man may eat of it and not die. I am the living bread which came down from heaven; if any one eats of this bread, he will live for ever; and the bread which I shall give for the life of the world is My flesh." (John 6:48-51)
