Philippians 2:22
But <1161> ye know <1097> (5719) the proof <1382> of him <846>, that <3754>, as <5613> a son <5043> with the father <3962>, he hath served <1398> (5656) with <4862> me <1698> in <1519> the gospel <2098>.
τὴν δὲ δοκιμὴν αὐτοῦ γινώσκετε, ὅτι ὡς πατρὶ τέκνον σὺν ἐμοὶ ἐδούλευσεν εἰς τὸ εὐαγγέλιον.
