26 But the Comforter, [which is] the Holy Spirit [Ruach HaKodesh], 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.

27 Peace I leave with you, my peace I give unto you: not as the world gives, give I unto you. Let not your heart be troubled, neither let it be afraid.
