Luke 17:23

they shall say, See here . . . go not, &c.--a warning to all so-called expositors of prophecy and their followers, who cry, Lo there and see here, every time that war breaks out or revolutions occur.

In this chapter we have, I. Some particular discourses which Christ had with his disciples, in which he teaches them to take heed of giving offence, and to forgive the injuries done them (Luk 17:1-4), encourages them to pray for the increase of their faith (Luk 17:5, Luk 17:6), and then teaches them humility, whatever service they had done for God (Luk 17:7-10). II. His cleansing ten lepers, and the thanks he had from one of them only, and he a Samaritan (Luk 17:11-19). III. His discourse with his disciples, upon occasion of an enquiry of the Pharisees, when the kingdom of God should appear (v. 20-37).

17:23-24 People will tell you, ‘Look, there is the Son of Man’: False Messiahs have arisen throughout history, but expectations for the Messiah were particularly high in the first century, as a variety of figures claimed to be God’s agents of deliverance (see Acts 5:36-37; 21:38). Jesus warned his disciples not to follow these imposters. • For as the lightning flashes: Lightning lights up the whole sky and is visible to everyone in the area. Similarly, when Jesus suddenly returns, it will be evident to everyone.
