'Lifted Up' in the Bible

Just as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up,

So Jesus told them, "When you have lifted up the Son of Man, then you will know that I AM, and that I do nothing on my own authority. Instead, I speak only what the Father has taught me.

As for me, if I am lifted up from the earth, I will draw all people to myself."

Then the crowd answered him, "We have learned from the Law that the Messiah remains forever. So how can you say that the Son of Man must be lifted up? Who is this Son of Man?"
