The blessing that Jesus promised was that the Master would serve His servants. This was unthinkable in Jesus" world (cf. John 13:3-8). However, Jesus enforced its certainty with a strong affirmation that Luke did not record Him using since Luke 4:24. The messianic banquet on earth at the beginning of the millennium is evidently in view here. [source][source][source]
"Eschatological fulfillment, and specifically sharing in God"s reign, is repeatedly pictured in terms of a festive meal in Luke. This association must be considered when interpreting the meal scenes and references to a future meal in the gospel, which have an unusually prominent place in Luke"s account of the ministry of Jesus."

Messiah will continue to serve His people during the messianic kingdom, but He will honor the faithful especially. The second watch was from9:00 p.m. to midnight, and the third watch was from midnight to3:00 a.m. by Jewish reckoning. These periods present the present world as a place of darkness in which a disciple can sleep rather than bear witness. [2][source]
