When the Advocate comes, whom I will send to you from the Father—the Spirit of truth who proceeds from the Father—He will testify about Me.
Textus Receptus (TR) - John 15:26 >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·
