Matthew 10:5–6
First one must preach to the Jews. The promises had been made to them, that from them Christ was going to appear according to the flesh; and when they disobeyed, then one must go to the nations. He joins the Samaritans to those from the nations, since they too were from the nations by race — Babylonians who settled Judea.
It is just that the word be preached to the Jews first, since the promises were first toward them, and since from them Christ appeared according to the flesh. But when they disobeyed, it was necessary to go to the nations. He joins the Samaritans to those from the nations as themselves also being from the nations and having settled Judea (Matthew 10:5–6).
Greek
Ὅτι δεῖ πρῶτον τοῖς Ἰου δαίοις κηρύττειν· πρὸς αὐτοὺς γὰρ ἦσαν γεγονυῖαι αἱ ἐπαγγελίαι, ὅτι ἐξ αὐτῶν ἤμελλεν ὁ Χριστὸς τὸ κατὰ σάρκα ὀφθῆναι καὶ ὅταν ἠπείθησαν, τότε εἰς τὰ ἔθνη χω ρῆσαι. Σαμαρείτας δὲ συνάπτει τοῖς ἐξ ἐθνῶν, ἐπειδὴ καὶ ἐξ ἐθνῶν ἦσαν κατὰ γένος Βαβυλώνιοι ὄντες καὶ οἰκήσαντες τὴν Ἰουδαίαν. ∆ίκαιον γάρ ἐστι πρὸς Ἰου δαίους πρῶτον κηρυχθῆναι τὸν λόγον, ἐπεὶ καὶ πρὸς ἐκείνους αἱ ἐπαγγελίαι πρῶτον, καὶ ὅτι ἐξ αὐτῶν ὁ Χριστὸς τὸ κατὰ σάρκα ἐφάνη. ὅτε δὲ ἠπείθησαν, ἀναγ καῖον ἦν εἰς τὰ ἔθνη χωρῆσαι. συν άπτει δὲ τοῖς ἐξ ἐθνῶν τοὺς Σαμαρείτας ὡς ἐξ ἐθνῶν ὑπάρ χοντας καὶ αὐτοὺς καὶ τὴν Ἰου δαίαν οἰκήσαντας.
