John 12:32

Then it will be in that day, That the nations will seek the root of Jesse, Who will stand as a standard for the peoples; And His resting place will be glorious.

“No one can come to Me unless the Father who sent Me draws him; and I will raise him up on the last day.

So Jesus said, “When you lift up the Son of Man, then you will know that I am He, and I do nothing from Myself, but I speak these things as the Father taught Me.

The crowd then answered Him, “We have heard from the Law that the Christ is to remain forever; and how do You say, ‘The Son of Man must be lifted up’? Who is this Son of Man?”

in order that the word of Jesus which He spoke would be fulfilled, signifying by what kind of death He was about to die.
