'Son of Man' in the Bible

and he said to him, I declare unto you, hereafter you shall see heaven open, and the angels of God ascending, and descending upon the son of man.

for no man hath penetrated into the secrets of heaven, but he that came down from heaven, even the son of man, who is in heaven.

but 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.

work not for the food which perisheth, but for that which endureth unto everlasting life, and which the son of man shall give unto you, for to him it is that the father, that is God, has given his credentials.

but Jesus answer'd, I assure you, except ye eat the flesh of the son of man, and drink his blood, ye will have no life in you.

what if you should see the son of man ascend up where he was before?

Jesus said therefore to them, when ye have lift up the son of man, then shall ye know what I am, and that I do nothing of my self, but speak as my father hath instructed me.

but Jesus answered them, saying, the time is come, when the son of man is to be glorified.

Upon which the people said to him, we have learnt from the law, that the Messiah is to live for ever: why do you say then, the son of man must be lift up? who is this son of man?

When he was gone, Jesus said, now is the son of man glorified, and God is glorified by him.
