καὶ εἰσῆλθεν εἰς τὸν οἶκον Ζαχαρίου καὶ ἠσπάσατο τὴν Ἐλεισάβετ.
Luke had this simple meeting between Mary and Elizabeth. Luke said that Mary entered the house of Zechariah (καὶ εἰσῆλθεν εἰς τὸν οἶκον Ζαχαρίου). Then she greeted or paid her respects to Elizabeth (καὶ ἠσπάσατο τὴν Ἐλεισάβετ), as anyone would. Apparently, these cousins knew each other, but how is not clear.
