But when the Comforter is come, whom I will send to you from the Father, even the Spirit of truth, which proceeds from the Father, he shall testify of me:
But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatever I have said to you.
Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come to you; but if I depart, I will send him to you.
And, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, said he, you have heard of me.
