Luke 12:40

Jesus concluded by applying the illustrations. By using the title "Son of Man" Jesus may have been implying that the coming of the Son of Man that Daniel had predicted was in view (Daniel 7:13-14). That prophecy dealt with His coming in glory to rule. Elsewhere Jesus said He did not know the time of His return (Matthew 24:36). However, it would be unexpected because the exact day and hour were unknown, and His return would surprise many people (cf. Matthew 24:36; Matthew 24:42; Matthew 24:44; Matthew 25:13; Mark 13:32-33; Mark 13:35).
