'Comforter' in the Bible

Then I returned and saw all the oppressions that are done under the sun: and, behold, the tears of such as were oppressed, and they had no comforter; and on the side of their oppressors there was power; but they had no comforter.

Her filthiness was in her skirts; she remembered not her latter end; Therefore is she come down wonderfully; she hath no comforter: Behold, O Jehovah, my affliction; for the enemy hath magnified himself.

For these things I weep; mine eye, mine eye runneth down with water; Because the comforter that should refresh my soul is far from me: My children are desolate, because the enemy hath prevailed.

And I will pray the Father, and he shall give you another Comforter, that he may be with you for ever,

But the Comforter, even the Holy Spirit, whom the Father will send in my name, he shall teach you all things, and bring to your remembrance all that I said unto you.

But when the Comforter is come, whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, he shall bear witness of me:

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 unto you; but if I go, I will send him unto you.
