'I Go Away' in the Bible

Then He again said to them, I go away, and you will seek me, and you will die in your sin: whither I go you are not able to come.

Then the Jews were saying, Whether will He kill Himself, because He says, Whither I go away, you are not able to come?

You heard that I said to you, I go away, and I come to you. If you love me with divine love, you would rejoice, because I go to my Father: because the Father is greater than I.
