John 15:27 WEB

²⁵  But this happened so that the word may be fulfilled which was written in their law, 'They hated me without a cause.'

²⁶  'When the Counselor{Greek Parakletos: Counselor, Helper, Advocate, Intercessor, and Comfortor.} has come, whom I will send to you from the Father, the Spirit of truth, who proceeds from the Father, he will testify about me.

²⁷  You will also testify, because you have been with me from the beginning.
