To return (ἔρχομαι erchomai)

Therefore, be vigilant. For you do not know at what hour your Lord will return. But know this: if only the father of the family knew at what hour the thief would arrive, he would certainly keep vigil and not permit his house to be broken into. For this reason, you also must be prepared, for you do not know at what hour the Son of Man will return. (Mt 24:42-44)

γρηγορεῖτε οὖν ὅτι οὐκ οἴδατε ποίᾳ ἡμέρᾳ ὁ κύριος ὑμῶν ἔρχεται. ἐκεῖνο δὲ γινώσκετε ὅτι εἰ ᾔδει ὁ οἰκοδεσπότης ποίᾳ φυλακῇ ὁ κλέπτης ἔρχεται ἐγρηγόρησεν ἂν καὶ οὐκ ἂν εἴασεν διορυχθῆναι τὴν οἰκίαν αὐτοῦ. διὰ τοῦτο καὶ ὑμεῖς γίνεσθε ἕτοιμοι ὅτι ᾗ οὐ δοκεῖτε ὥρᾳ ὁ υἱὸς τοῦ ἀνθρώπου ἔρχεται.

vigilate ergo quia nescitis qua hora Dominus vester venturus sit. illud autem scitote quoniam si sciret pater familias qua hora fur venturus esset vigilaret utique et non sineret perfodiri domum suam. ideoque et vos estote parati quia qua nescitis hora Filius hominis venturus est.
