'Son of Man' in the Bible

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

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

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

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

Labour not for the meat which perisheth, but for that meat which endureth unto everlasting life, which the Son of man shall give unto you: for him hath God the Father sealed.

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

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

Then said Jesus unto them, When ye have lifted up the Son of man, then shall ye know that I am he, and that I do nothing of myself; but as my Father hath 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 abideth for ever: and how sayest thou, 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.
