Luke 17:22-23

Jesus next gave His disciples more instruction about the coming of the kingdom. One of the days of the Son of Man refers to one of the future days when the Son of Man will be reigning on the earth (cf. Luke 17:24-25; Luke 17:30), perhaps the first day. [Note: Plummer, p. 407.] The use of "Son of Man" recalls Daniel 7:13-14 that predicts the earthly reign of Messiah. The disciples would desire to see the kingdom come because they would experience persecution before Jesus returned. There would be many false alarms about His return, but disciples should not allow others to mislead them (cf. Matthew 24:23; Mark 13:21).
