'Son of Man' in the Bible

And he said unto him, Verily, verily, I say unto you, Hereafter you shall see heaven opened, and the angels of God ascending and descending upon the Son of man.

And no man has ascended up to heaven, but he that came down from heaven, even the Son of man who is in heaven.

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

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

Labor not for the food which perishes, but for that food which endures unto everlasting life, which the Son of man shall give unto you: for on him has God the Father set his seal.

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

What if you shall see the Son of man ascend up where he was before?

Then said Jesus unto them, When you have lifted up the Son of man, then shall you know that I am he, and that I do nothing of myself; but as my Father has taught me, I speak these things.

And Jesus answered them, saying, The hour is come, that the Son of man should be glorified.

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

Therefore, when he was gone out, Jesus said, Now is the Son of man glorified, and God is glorified in him.
