Our fathers ate the manna in the wilderness. As it is written, 'He gave them bread out of heaven{Greek and Hebrew use the same word for "heaven", "the heavens", "the sky", and "the air".} to eat.'"

 That is why Jesus can satisfy the eternal hunger. He is sealed by God, he is God's truth incarnate and it is God alone who can truly satisfy the hunger of the soul which he created.
