Luke 12:47 - Ellicott's Commentary On The Whole Bible

And that servant, which knew his lord’s will. — The verses that follow (Luke 12:47-50) are peculiar to St. Luke, and every word is full of profoundest interest. First there comes a warning to the disciples who knew their Lord’s will, who had been told to watch for His coming, to prepare themselves and others for it. That “will” included the use of all gifts and opportunities, as in the parables of the Pounds and the Talents, with faithfulness and activity in using them. On those who, with their eyes open, were sinning against light and knowledge (our Lord’s words had, we can scarcely doubt, a latent reference to Judas) there should come, in this world or in the world to come, a penalty proportionably severe.
