The thief (o klepthv). The change here almost makes a new parable to illustrate the other, the parable of the housebreaking (verses Luke 12:39-40) to illustrate the parable of the waiting servants (Luke 12:35-38). This same language appears in Matthew 24:43 f. "The Master returning from a wedding is replaced by a thief whose study it is to come to the house he means to plunder at an unexpected time" (Bruce). The parallel in Matthew 24:43-51 with Luke 12:39-46 does not have the interruption by Peter.
He would have watched (egrhgorhsen an). Apodosis of second-class condition, determined as unfulfilled, made plain by use of an with aorist indicative which is not repeated with ouk afhken (first aorist active indicative of afihmi, k aorist), though it is sometimes repeated (Matthew 24:43).
