Luke 12:40

Καὶ ὑμεῖς οὖν γίνεσθε ἕτοιμοι· ὅτι ᾗ ὥρᾳ οὐ δοκεῖτε ὁ υἱὸς τοῦ ἀνθρώπου ἔρχεται.

RBT Translation:

And you, yourselves, become prepared, because to her whom you are not thinking of, a seasonal time, the Son of the Man is coming!

Julia Smith Literal 1876 Translation:
And be ye therefore ready: for in the time which ye think not the Son of man is coming.

LITV Translation:
And you, then, be ready; for in the hour you think not, the Son of man comes.
