John 3:14; John 8:28; John 12:32; John 12:34

14 And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up :
28 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.
32 And I, if I be lifted up from the earth, will draw all men unto me.
34 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?
