John 15:26
Patriarchal Greek New Testament (1904) · Berean Standard Bible
ὅταν δὲ ἔλθῃ ὁ παράκλητος ὃν ἐγὼ πέμψω ὑμῖν παρὰ τοῦ πατρός, τὸ Πνεῦμα τῆς ἀληθείας ὃ παρὰ τοῦ πατρὸς ἐκπορεύεται, ἐκεῖνος μαρτυρήσει περὶ ἐμοῦ·
When the Advocate (note: Or Comforter or Helper or Counselor; Greek Paraclete) comes, whom I will send to you from the Father—the Spirit of truth who proceeds from the Father—He will testify about Me.
