John 16:5-7

But I told you not these things from the beginning, because I was with you. And now I go to him that sent me, and none of you asketh me: Whither goest thou?

But because I have spoken these things to you, sorrow hath filled your heart.

But I tell you the truth: it is expedient to you that I go. For if I go not, the Paraclete will not come to you: but if I go, I will send him to you.
