John 15:19 — ExegesisTAB

The verse is built as a contrary-to-fact condition. The opening ei {εἰ | ei} clause with ete {ἦτε | ē-te} sets up an unreal premise about origin and belonging, while the apodosis uses an {ἂν | an} with ephilei {ἐφίλει | e-phi-lei} to express the hypothetical outcome that would have followed from that premise. The phrase to idion {τὸ ἴδιον | to idion} functions as a substantive object, stressing that the world naturally embraces what it regards as belonging to itself. The transition hoti de {ὅτι δὲ | hoti de} introduces the actual situation and sharpens the contrast: the repeated ek tou kosmou {ἐκ τοῦ κόσμου | ek tou kosmou} marks origin and separation, showing that the disciples do not derive their identity from that sphere. The strong adversative allʼ {ἀλλʼ | all} pivots to the speaker’s decisive agency, with ego {ἐγώ | e-go} placed for emphasis before exelexamen {ἐξελεξάμην | ek-se-le-xa-men}, making the act of choosing the interpretive center of the sentence. The final dia touto {διὰ τοῦτο | dia touto} is inferential, not merely temporal, and explains the present hostility summarized by misei {μισεῖ | mi-sei}. The repeated kosmos {κόσμος | kosmos} at the beginning and end gives the verse a ring-like rhetorical frame, so the whole statement moves from unreal belonging, to actual separation, to the consequence of that separation.
