'Son of Man' in the Bible

Jesus answered and said to him: Do you believe, be cause I said to you, I saw you under the fig-tree? You shall see greater things than these. And he said to him: Verily, verily I say to you, From this time you shall see heaven opened, and the angels of God ascending and descending upon the Son of man.

And no man has ascended into heaven, but he who came down from heaven, the Son of man, who is in heaven.

And as Moses lifted up the serpent in the wilderness, so must the Son of man be lifted up;

and he has given him authority to execute judgment also, because he is the Son of man.

Labor not for the food that perishes, but for the food that endures to life eternal, which the Son of man will give you; for him has God the Father at tested.

Then Jesus said to them: Verily, verily I say to you, Unless you eat the flesh of the Son of man, and drink his blood, you have no life in you.

Then, what if you should see the Son of man go up where he was before?

Then said Jesus to them: When you have lifted up the Son of man, then you will know that I am He, and that I do nothing of myself, but as the Father has taught me I speak these things.

But Jesus answered them, saying: The hour has come that the Son of man must be glorified.

The multitude answered him: We have heard out of the law, that the Christ remains forever: and how say you that the Son of man must be lifted up? Who is this Son of man?

When he had gone out, Jesus said: Now is the Son of man glorified, and God is glorified in him.
