26 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, whatsoever I have said unto you. (John 14:26)

26 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 testify of me: (John 15:26)

Ruach ha-Kodesh is the Comforter. He is the Spirit of truth.

What did Israel know about the Comforter and comfort?

12 I, even I, am he that comforteth you: who art thou, that thou shouldest be afraid of a man that shall die, and of the son of man which shall be made as grass; (Isaiah 51:12)

1 The Spirit of the Lord GOD is upon me; because the LORD hath anointed me to preach good tidings unto the meek; he hath sent me to bind up the brokenhearted, to proclaim liberty to the captives, and the opening of the prison to them that are bound;
2 To proclaim the acceptable year of the LORD, and the day of vengeance of our God; to comfort all that mourn;
3 To appoint unto them that mourn in Zion, to give unto them beauty for ashes, the oil of joy for mourning, the garment of praise for the spirit of heaviness; that they might be called trees of righteousness, the planting of the LORD, that he might be glorified. (Isaiah 61:1-3)

16 For these things I weep; mine eye, mine eye runneth down with water, because the comforter that should relieve my soul is far from me: my children are desolate, because the enemy prevailed. (Lam. 1:16)

"What is his [the Messiah's] name? — The School of R. Shila said: His name is Shiloh, for it is written, until Shiloh come. The School of R. Yannai said: His name is Yinnon, for it is written, His name shall endure for ever: e'er the sun was, his name is Yinnon. The School of R. Haninah maintained: His name is Haninah, as it is written, Where I will not give you Haninah. Others say: His name is Menahem the son of Hezekiah, for it is written, Because Menahem ['the comforter'], that would relieve my soul, is far." (Sanhedrin 98b http://www.come-and-hear.com/sanhedrin/sanhedrin_98.html)

1 Comfort ye, comfort ye my people, saith your God. (Isaiah 40:1)

9 Break forth into joy, sing together, ye waste places of Jerusalem: for the LORD hath comforted his people, he hath redeemed Jerusalem. (Isaiah 52:9)

13 As one whom his mother comforteth, so will I comfort you; and ye shall be comforted in Jerusalem. (Isaiah 66:13) etc.
